Abstract:

In the present work turbulent thermal and hydrodynamic behaviors of fluid flow in microchannel is investigated numerically using modified k-epsilon model. Different micro-geometries are adopted in this study such as microtubes, isothermal micro two fixed plates and micro Couette flow. The numerical procedure is developed in the present work based on the control volume approach proposed by Patankar. Validation between numerical and experimental or analytical hydrodynamics and thermal behaviors is investigated. It is found that this numerical technique gives the same predictions which are given by the experimental or analytical.
