• Abstract

The aim of the present investigation is to study numerically the heat transfer and flow characteristics for the buoyancy induced flow through inclined tubes. Mass, Momentum and energy equations were solved by finite difference approach. Constant heat flux boundary condition is created at the tube surface. Heat transfer and flow characteristics were calculated for various system parameters like tube length, tube diameter, tube inclination and heat flux supplied. The heat transfer coefficient and the induced flow rate both were found increasing with increase in the angle of inclination and heat flux supplied. The flow rate of water is found to increase with increase in the pipe length and tube diameter. The results obtained numerically were compared with the experimental data and were found within 10% agreement with each other.
