Analysis of Heat Transfer during Liquid-Vapor Pulsating Flow in a U-Shaped Miniature Channel
ABSTRACT
Heat transfer during liquid-vapor pulsating flow in a vertically placed U-shaped miniature channel is analytically investigated. The heating sections are near the two sealed ends and the cooling section is located in the middle of the channel. The governing equations for pulsating flow as well as sensible and latent heat transfer are nondimensionalized and the problem is described using seven dimensionless parameters. The dimensionless governing equations for pulsating flow are solved using the Runge-Kutta method while temperature distribution in the liquid slug is obtained by using an implicit finite difference scheme. Effects of various dimensionless parameters on the heat transfer of the system are discussed.
