Numerical Simulation of the Heat Transfer Performance in Heat Exchanger Inserted by Disturbance Device

Abstract:

A new heat exchange pipe—heat exchanger inserted by disturbance device has been introduced. By applying commercial software—Fluent, the heat transfer and the flow performance of the heat exchanger which is a three-dimension numerical simulation in which the medium is air have been simulated, With simulation analysis of flow field in the heat exchanger，the enhanced transfer mechanism has been got; Using the heat transfer efficiency j/f, nine different models with different bending curvature and column spacing have been analyzed. Through analyzing the impact of the heat transfer and the flow performance on different bending curvature and column spacing, the best combination is achieved. Providing a certain theoretical basis, for research and design new type of heat exchanger pipes.
