The authors conduct a mathematical analysis of the film condensation regime in a heat-pipe-based vapor condenser for determining optimum heat transfer coefficients in the heat exchanger and heat transfer fluid under conditions of laminar flow. The model incorporates heat transfer fluid properties such as surface tension, vaporization heat, viscosity, wave formation and instability and specific heat, and condenser properties such as heat flux density and surface area. Mathematical parameters of the model include Reynolds number, Nusselt number, Prandtl number, and Kapitza resistance. The model is intended for the parametric optimization of vapor condenser thermal efficiency and is tested, in this paper, against experimental data for water and freons.
