Two-Dimensional Analysis Model of a Pulse Tube
맥동관의 2차원 해석모델
Abstract
Enthalpy transport in a pulse tube was investigated by two-dimensional analysis of mass, momentum and energy equations of the gas as well as energy conservation of the tube wall. The mean temperature of the gas and the tube wall was obtained directly by assuming that the outer surface of a pulse tube is adiabatic. Effects of operating frequency, tube wall thickness, velocity ratio and velocity phase angle between both ends of a pulse tube on net enthalpy flow were shown.
