In this paper the two-dimensional flow of a micropolar fluid through porous medium over a continuously moving porous vertical plate under the combined buoyancy effects of thermal and heat source has been studied under the action of transverse magnetic field taking into account the thermal radiation field. The Roseland approximation is used to describe radiative heat transfer in the limit of opt...

In many applications, the heat flux at surface is known instead of temperature. addition, in some like vacuum drying or high altitude flights, pressure below atmospheric pressure, so rarefaction effects become important, and therefore, Navier-Stokes-Fourier equations fail to predict gas thermal behavior. this paper, a constant boundary condition developed implemented frame Shakhov model kinetic...

Paolo Di Marco Walter Grassi Dipartimento di Energetica, Universit?~ di Pisa, Pisa, Italy • The purpose of the paper is to experimentally assess the effect exerted by subcooling degree and heat-up rate (i.e., the rate of increase of thermal flux) on the phenomenon of nucleate boiling in the presence of an electric field. To this aim, an experimental facility was set up to investigate pool boili...

the vehicle braking system is considered to be one of the most fundamental safety-critical systems in modern vehicles, as its main purpose is to stop or decelerate the vehicle. the frictional heat generated during braking application can cause numerous negative effects on the brake assembly, such as brake fade, premature wear, thermal cracks and disc thickness variation. in the past, surface ro...

The aim of this paper is to enhance thermal performance of a microchannel heat sink by using nanoencapsulated phase change material (NEPCM) slurry as a cooling fluid instead of pure fluid. A threedimensional model of a circular channel using water slurry of NEPCM was developed. The results show a significant reduction in the mean fluid temperature along the channel and heat sink wall temperatu...

Land surfacemodels (LSMs) are often applied to predict the one-way coupling strength between surface soil moisture (SM) and latent heat (LH) flux. However, the ability of LSMs to accurately represent such coupling has not been adequately established. Likewise, the estimation of SM/LH coupling strength using ground-based observational data is potentially compromised by the impact of independent ...

Lie symmetry method is applied to find analytic solutions of initial-boundaryvalue problems of transient conduction in semi-infinite solid with constant surface temperature or constant heat flux condition. The solutions are obtained in a manner highlighting the systematic procedure of extending the symmetry method for a PDE to investigate BVPs of the PDE. A comparative analysis of numerical and...
