|
In present day it is necessary to optimize the heat transfer characteristic of heat exchangers, as heat exchangers are universal equipments which are used in day to day life, in industry, home appliances, transportations and power production units. Thermal characteristics are studied for the tube in the shell and tube heat exchanger working with water as working fluid for two different configurations of twisted tape.1)Twisted tapes and 2)Soldered wire wound inserts(wire wound wire matrix). Experiment was carried out by using these two types of inserts on the tube side. This project work deals with laminar flow in the tube side; Re varies from 200 to 600. Experiment carried out by maintaining the constant tube wall temperature with tube flow rate and shell flow constant. Twisted tapes used in this experiment have 2.2 twist ratio, and. The heat transfer and pressure drop in case of twisted tape and Soldered wire wound inserts with baffles are found to increase by 110 to 120% and 130 to 140% respectively compared to that of plain tube. |
