CFD ANALYSIS OF HEAT TRANSFER TO THE FLOWING FLUIDIN A CLOSE CONDUIT AT CONSTANT HEAT FLUX

Abstract

Heat Transfer is the most important phenomena in engineering application. Complete recovery of heat is a challenging task. Different people opt for different option for heat recovery. The most important parameter in heat transfer is heat transfer coefficient. Higher the value of heat transfer coefficient higher is heat transfer from the system. The objective of the dissertation is to study the effect on heat transfer in pipe and pipe having different flow cross section using ANSYS. To achieve this pipe of length 1.5 meter is taken. The fluid is flowing full in pipe. The different parameters like pressure, velocity, temperature, and heat flux and heat transfer coefficient are found out using simulation at various cross sections along the flow. The cross section is at 0.3, 0.6, 0.9, 1.2 and 1.5 meters respectively. The simulations are carried out at different mass flow rates.
