CFD Analysis of Turbulent Heat Transfer through Rectangular Channel on Shape Optimization of Different Dimple Shape
-Manjit Kumar ; Pankaj Shrivastava
Conventional sources of energy have been depleting at an alarming rate, which makes further sustainable fulfillment of requirement of energy very difficult. Thus, heat transfer enhancement technology plays an important role and it has been widely applied to many applications as in refrigeration, automotive, process industry and solar energy heater. Convective heat transfer can be enhanced passively by changing flow geometry, or by increasing heat transfer coefficient between the heat transferring surface and the heat carrier fluid. Another possibility for increasing heat transfer to fluid is to employ extended surfaces. The use of dimple as fins in a duct increases the heat transfer area and breaks the laminar sub-layer creating local wall turbulence. The heat transfer rate is improved but pressure drops is increased as well. A numerical investigation has been performed to study the effects of different dimple shapes on heat transfer and fluid flow characteristics through transversely roughened rectangular channels for Reynolds number ranging from 10000 to 30000 and subjected to uniform heat flux of 1000 W/m2. Considering single-phase approach, the two-dimensional continuity, Navier-Stokes, and energy equations developed for the physical model have been solved by using the finite volume method (FVM). The optimization was carried out by using various dimple shapes (rectangular, triangular, wedge pointing upstream, and wedge pointing downstream) in in-line and six different aspect ratios (w/e = 5, 3.334, 2.5, 2, 1.667 and 1) to reach the optimal geometry of the dimple with maximum Performance Evaluation Criterion (PEC). The highest PEC was obtained for the triangular dimple channel with w/e = 1.667 (i.e. dimple height e = 6mm & w = 10mm) at Re = 10000. Read More...

-Zaid Pathan ; Shreyas Reddy; Taha Rizvi; Rahul Jain
The Internet is a global, common and self-sufficient structure available to billions of people around the world. Huge amount of data is stored in a structured format. When the user looks for data in the search engine, it returns huge volume of relevant and irrelevant data. The returned queries are arranged with the help of certain parameters, wherein number of visits being one of them. Due to this, the new sites having higher relevancy, but less number of visits suffer and hence are ranked low. This is referred as cold start problem. To overcome this problem, we propose a two-stage Smart Crawler, to extract the relevant data from the Invisible Web. This module returns seed sites from the site database. In the first stage, this framework performs a 'reverse lookup' that matches the users’ query with URL. In the second stage, the 'prioritization of incremental sites' is performed as per the content of the query. The returned links are classified as relevant and irrelevant links, and high ranked links are shown on the results page. Our proposed model efficiently returns deep web interfaces from a pool of sites and achieves better results than other crawlers, as well as eliminates the cold start problem by returning only relevant data. To achieve performance, we design 'custom search' where the user gets data based on their profession. Read More...

Selection of Building Contractor by Analytical Hierarchy Process (AHP)
-Abhishek Bramhankar
One of the key activities of any client is selection of appropriate contractor. Without a suitable method and technique for selecting the best contractor, the completion of a project will likely be affected. In this study, we examine the use of the analytical hierarchy process (AHP) as a multi criteria decision making model for selection of appropriate contractor. This method can assist project management teams in identifying contractors who are most capable to deliver satisfactory outcomes in a selection process that is not based simply on the lowest bid. In this study, an AHP-based model is tested using a hypothetical scenario in which three contractors are evaluated. Six criteria for the primary objective are evaluated. These criteria’s are identified for contractor selection in the process, and the significance of each criterion is determined using a questionnaire survey. Comparisons are made by ranking the aggregate score of each contractor based on each criterion, and the contractor with the highest score is deemed the best. This study contributes to the construction sector in two ways: first, it extends the understanding of selection criteria to include degrees of importance, and second, it implements a multi-criteria AHP approach, which is a new method for analyzing and selecting the most appropriate contractor.

Model Tests to Determine Uplift Capacity of Combined Vertical and Batter Pile Groups Embedded in Sandy Soil
-Ram A. Dhankani ; M. G. Vanza
Foundations of some structures like transmission line towers, tall chimneys and many offshore structures are subjected to overturning moments due to wind load, seismic effect, wave load, ship impacts, etc. For foundations in such structures, generally a combination of vertical and batter piles are used. Batter piles provide a much stiffer resistance to horizontal and inclined loads than would be possible with vertical piles. Experimental model tests have been conducted on pile groups embedded in sandy soil and subjected to pure axial uplift loading. In the present study an attempt has been made to estimate the uplift capacity of combined vertical and batter pile groups embedded in sandy soil of uniform relative density of 63%. The model piles used in this investigation are mild steel solid shaft. The pile groups consisting of 2x2 piles (2 vertical and 2 batter piles), c/c spacing is 3d (d is diameter of pile) and slenderness ratio (L/d) of 8, 12 and 16. In pile groups the angle of batter piles is varied as 10Ëš, 20Ëš and 30Ëš. The influences of pile embedment depth, batter angle on the uplift capacity of piles are investigated. Results indicate that the pull out capacity of these pile groups increases with increasing the batter angle. The uplift capacity of pile group also increases with increase of slenderness ratio.

Aircraft Last Location Detector
-Rishabh Sharma ; Mr. M. S. Prasad
Air traffic has becoming the main part of transportation globally. It is also increasing with passage of time But the accident cause of the aircraft either on air or land causes the loss of life as well as aircraft structure. Recently many of the aircraft goes missing and there is no clue of single part of plane like Malaysia flight 370, Egypt MS 804, IAF AN32. So, the search operation takes place in a big area which takes lots time. One approach to eliminating the delay between accident occurrence and first responder dispatch is use in accident detection and notification system which senses when aircraft crash occur and immediately notify emergency personnel. The problem is that no such system in plane for locating or identifying where the crash takes place and responding the ones in charge of flight accident emergencies. Even with passage of time survival rate decreases. Therefore, the main object of the research is to come up with a system that could report the accident and give the actual location of the accident area and responder in short time. The other objectives are to review the accidents which help to investigate and solve the issue. This research introduces the new concept of usage of automatic accident reporting and notification system to their respective departments at the real time when the accident occur. Read More...

-Arun Prasath. N ; Dr. S. Muthu Vijaya Pandian; K. Geetha
As mobile devices continue to grow in popularity and functionality, the demand for advanced ubiquity mobile applications in our daily lives also increases. This pa per deals with the design and implementation of HASec, a Home Automation and Security system for mobile devices, that lever ages mobile technology to provide essential security to our homes and associated control operations. In particular, with the help of mobile devices, HASec operates and controls motion detectors and video cameras for remote sensing and surveillance, streams live video and records it for future playback, and finally manages operations on home appliances, such as turning ON/OFF a television or microwave or altering the intensity of lighting around the house. The proposed home security solution hinges on our novel integration of cameras and motion detectors into a mobile application. For instance, when motion is detected, the cameras automatically initiate recording and the iOS device alerts the homeowner of the possible intrusion. HASec has two main components interacting with each other: the iOS application that executes on the mobile device and serverside scripts that run in a cloud. Although HA-Sec is implemented for Apple's iOS devices such as iPhone, iPod Touch, and iPad, it can be easily ported to other mobile plat-forms. Furthermore, our application is not only limited to smart-phones but also can be used by feature phones through their browsers. Read More...
