Similarities are mathematical laws, which based on the dimensionless formulation of governing equation a physical phenomenon. Consequently, set characteristic numbers is obtained. aim, via these numbers, to find equivalences between particular configurations. This approach widely adopted, especially in fluid and aerodynamic problems. In building context, phenomena heat mass transfer porous medi...

The interaction of thermal radiation with conduction and laminar natural convection in a vertical circular pin, situated at participating gas, is numerically investigated. An absorbing and emitting gas is considered, and treated to be a gray participating media. Under the idealizing of gray gas, the Rosselan4 approximation is employed to describe the radiative heat flux in the energy equation. ...

The understanding of the underlying dynamical mechanisms which determine the macroscopic laws of heat conduction is a long standing task of non-equilibrium statistical mechanics. A better understanding of the mechanism of heat conduction may lead to potentially interesting applications based on the possibility to control the heat flow. Indeed, different models of thermal rectifiers has been rec...
