摘要：

The present work is an investigation of the developing gas flow and heat transfer through a wavy micro-channel. Computational fluid dynamics ( CFD) is used to solve the fluid flow and energy equations along with the slip flow and temperature jump boundary conditions. The simulations are carried out using three wavy amplitudes for Knudsen number 0.025 to 0.1 in the slip flow regime. It is shown that increasing the wavy amplitude results in augmentation of the heat transfer rate at the cost of increasing the frictional losses. However, the rarefication has a declining effect on both friction factor and Nusselt number. Correlations for the friction factor and Nusselt number as function of amplitude and Knudsen number are provided. (C) 2016 Jordan Journal of Mechanical and Industrial Engineering.
