CFD SIMULATION AND EXPERIMENTAL VERIFICATION OF AIR FLOW THROUGH HEATED PIPE

The aim of this work is to validate the Dittus-Boelter equation by experimental, correlation and Simulation method. It used to find the value of heat transfer coefficient ‘h’ for turbulent flow in many fluid transfer systems. This work discusses how the Dittus-Boelter equation is applied to the problem of circular pipe. In CFD simulation ICEM CFD for modeling and CFX13 for analysis are used. Results of CFD simulation will be obtained by CFD-POST. Here heat transfer coefficient value is compared by correlations, experiment and CFD simulations for various model, finally the aim of this work is to validate Dittus-Boelter equation.
