Design and Performance Enhancement of Induced Draft Counter Flow Wet Type Cooling Tower

Cooling towers are one of the biggest heat and mass transfer devices used to transfer process waste heat to the atmosphere. Cooling towers make use of evaporation whereby some of the water is evaporated into a moving air stream and subsequently discharged into the atmosphere. As a result, the remainder of the water is cooled down significantly. The process parameters such as inlet Air Wet bulb Temperature, Flow rate of Water and fills porosity have more influence on Thermal performance of cooling tower. The Temperature of outlet water is maintained nearest to inlet air wet bulb temperature to obtain the best Thermal Performance of cooling tower. Finite element method is one of the powerful numerical techniques to solve the complex physical phenomenon that are governed by the differential equations. Many of the practical engineering problems such as structural, thermal, magnetic, acoustic, etc. can be solved by the finite element method. Moreover, the finite element method is an increasingly common tool for engineering design. Design and dimension are taken from Dishman Pharmaceutical And Chemical Limited,Naroda GIDC, Ahmedabad, Gujarat. In this research work my objective is to get optimum condition which gives the maximum effectiveness in counter flow FRP cooling tower. For effectiveness parameters like inlet water flow rate, inlet air rate and fill porosity are considering in this research. So optimization of heat transfer is done by using taguchi method. Taguchi method is reducing the number is experiment. Here also used the Minitab software for taguchi method. For this model of cooling tower is made in Creo 2.0 then convert this model in STEP file and imported in ANSYS Workbench for CFD analysis. In this paper present the CFD analysis of cooling tower and comparing this result to practical reading. For taking practical reading temperature sensor and thermocouple is used.
