Heat transfer including heat conduction, thermal convection, and radiation is a major transport process that occurs in various engineering natural systems such as exchangers, solar collectors, nuclear reactors, atmospheric boundary layers, electronical biomedical systems, others [...]

This paper is focused on the application of hybrid Single relaxation time lattice Boltzmann and finite volume methods in conjunction with discrete ordinates method to simulate coupled natural convection and volumetric radiation in differentially heated enclosure, filled with an absorbing, emitting and non-scattering gray medium. In this work, the velocity and temperature fields are calculated u...

Convection, conduction, and thermal radiation are the three mechanisms of heat transfer in nature. The lattice Boltzmann model (LBM) has already achieved great success dealing with convection conduction problems. However, mature LBM for radiative (RHT) is still relatively lacking. Here we propose a mesoscopic RHT graded-index media, which enables simple efficient solution both transient steady-...

The effect of thermal radiation on the natural convection flow along a uniformly heated vertical porous plate with variable viscosity and uniform suction velocity was investigated numerically. The fluid considered in this study is of an optically dense viscous incompressible fluid of temperature-dependent viscosity. The laminar boundary layer equations governing the flow are shown to be nonsimi...

We report a combined theoretical and experimental investigation on the near field acoustic levitation (NFAL). In NFAL a disk is levitated at a height much smaller than the acoustic wavelength. The levitation force is induced by the gas squeeze film between the sound radiation surface and the levitated disk. By taking into account the flexural vibration of the sound radiation surface as well as ...
