MICROSCALE FLOW AND HEAT TRANSFER BETWEEN THE ROTOR AND THE FLANK FOR ROTARY ENGINE

ABSTRACT
This paper is to investigate microscale flow and transfer between the rotor and the flank for rotary engine. The rotor and flank are simplified to two disks in order to study flow field and temperature field conveniently. The paper takes analysis of steady laminar flow and heat transfer between two disks separated by a gas-filled gap due to machining tolerance. A 3-D multi-physical coupling model is used, involving velocity slip, temperature jump, rarefaction, and dissipation. A solution based on commercial code COMSOL is derived and the results are used to illustrate the effects to velocity field, temperature distribution, disks' torque, and Nusselt number based on the governing parameters. The paper also investigates the effects of different modified Knudsen number on flow field and temperature field.
