Computational Modeling and Simulation of Film-Condensation
Abstract
This report describes an investigation of modeling and analysis of two-phase flow in the condenser of a vapor-compression refrigeration system. The approach used a novel in-house code for the analysis of two different film condensation problems: a) underside of a horizontal plate, b) in a plane channel. In the first study, the effect on heat transfer was determined at various degrees of sub-cooling of the plate and at various unsteady flow regimes using R-123 and n-pentane as working fluids. The second study was done analytically for fully-developed and numerically for developing flow in a channel; excellent agreement between the two results was observed in the fully developed region. Simulations were done for four different cases, consisting of various standard thermal boundary conditions on the channel wall. Numerical results obtained for the developing flow are consistent with the physical-model and operating-conditions proposed in the present work. The findings from this fundamental modeling and simulation study can be extended to model and analyze condenser flow for better design and integration in thermal-management systems found in aircraft.
