چکیده
Flow boiling in microchannel heat sinks is considered as a promising cooling solution for electronic components. Higher flux can be effectively dissipated by the utilization of latent vaporization. However, most current studies on flow microchannels are mainly experimental investigations and two-dimensional numerical studies. In this paper, Volume Fluid (VOF) model combined with Lee evaporation-condensation phase change used to simulate HFE7100 horizontal three-dimensional conjugate simulation. The simulation results compared [1], showing an excellent agreement. pattern obtained. typical includes bubble flow, slug annular et al. addition, effect local wall superheat (ΔTloc) transfer coefficient (hloc) along direction discussed detail at constant mass flux. At entrance channel, temperature boundary layer thinner, higher coefficient. low flux, due lower microchannel. Furthermore, it observed that decreases tend reach value certain location. Overall, increases increasing This because more nucleation sites activated high thus enhance nucleate boiling. When 70 kW/m2, maximum average 10862 W/m2K. methods study provide guidance design sinks.

Numerical Simulation of Turbulent Subsonic Compressible Flow through Rectangular Microchannel
In this study, turbulent compressible gas flow in a rectangular micro-channel is numerically investigated. The gas flow assumed to be in the subsonic regime up to Mach number about 0.7. Five low and high Reynolds number RANS turbulence models are used for modeling the turbulent flow. Two types of mesh are generated depending on the employed turbulence model. The computations are performed for R...

متن کاملNumerical simulation of growth of a vapor bubble during flow boiling of water in a microchannel
The present study is performed to numerically analyze the growth of a vapor bubble during flow of water through a microchannel. The complete Navier– Stokes equations, along with continuity and energy equations, are solved using the SIMPLER (semi-implicit method for pressure-linked equations revised) method. The liquid–vapor interface is captured using the level set technique. The microchannel i...
