In this research, a numerical simulation is performed to investigate thermal and viscous irreversibilities for Al2O3-water nanofluid inside a duct equipped with porous baffles. The effects of different parameters including Reynolds number, Darcy...

The impetus of the current research is to use the direct simulation Monte Carlo (DSMC) algorithm to investigate fluid behaviour and gas transport in porous microchannels. Here, we demonstrate DSMC’s capability to simulate porous media up to 40...

Investigation of flow field and heat transfer from a rotating sphere is very important in fluid mechanics, astrophysics and astronautics. Besides, nowadays because of heat transfer characteristics of the porous medium and its lightness, they have...

By increasing the velocity of flow in coarse grain materials, local turbulences are often imposed to the flow. As a result, the flow regime through rockfill structures deviates from linear Darcy law; and nonlinear or ...

Variability of hydraulic parameters in coarse porous media...
