Melting Behaviors of Capric Acid in Rectangular Enclosure
摘要
Abstract
An enthalpy-porous model was used to simulate the melting behaviors of capric acid in a rectangular enclosure with a heated wall on one side. The simulation accuracy was verified by comparing the simulated results with those by experiment. The simulation results showed that average Nusselt number and its decreasing rate reduced gradually with an increase in Fourier number. An exponential function for melting volume fraction was regressed, the exponents of which for Stefan number, Rayleigh number and Fourier number were 0.663 5, 0.190 6, and 0. 853 5, respectively.关键词
