.... In this work, a two-dimensional simulation model of an LHP was developed. The wicking process was described using a capillary pressure model, implemented through user-defined functions (UDFs). The flow, phase change, and heat transfer processes vary with the change of the working fluid. Therefore, the effects...

..., along with equations representing turbulence flow effects and heat and mass transfer via phase change [ 63 – 66 ]. The most popular model for predicting phase change phenomena in OHPs is the volume of fluid (VOF) method [ 67 – 79 ]. VOF is a surface-tracking technique that solves a single set...

... includes an ac power supply, an external chiller, a stainless steel testing chamber, and a light source used for visualization of phase change. Phase change capability study of silicon wick structure is conducted in an open environment. As the schematic shown in Fig. 10 , the main body of the vacuum...
