In the current work, the effect of shear work due to the velocity slip on the non-equilibrium heat transfer in a pressure driven micro/nanochannel is evaluated under the constant wall heat flux boundary condition.As our simulation tool, the DSMC...

heat flux model is introduced for calculation of the absorbed heat flux by the solid, particle, and fluid phases. The effects of Nield number on the heat transfer are completely studied. The obtained results show that the heat flux at the wall absorbed...

/particle/solid phases, is employed in the porous channel. Moreover, one heat flux model is proposed. The fully-developed flow and steady Darcy-Brinkman equation is employed in the porous channel. The local thermal nonequlibrium model is assumed between fluid, particles...

Simulations are performed to investigate rarefaction effects on velocity, temperature, heat flux, shear stress and entropy

profiles. The specific contribution of this work is detailed discussion on heat flux and shear stress behavior of the gas...

Cooling and heating play a major role in micro/nano-devices and rarefied gases [1]. In this paper, we
