The paper aims at investigating the effects of chemical reaction and thermal radiation on the steady two-dimensional laminar flow of viscous incompressible electrically conducting micropolar fluid past a stretching surface embedded in a non-Darcian porous medium. The radiative heat flux is assumed to follow Rosseland approximation. The governing equations of momentum, angular momentum, energy, ...

natural convection heat transfer from a tube bundle in the indirect water bath heaters is investigated. a computer-code is used for the solution of the governing equations of mass, momentum and energy transfer based on the simple-c algorithm. simulations are carried out for the gas pressure station heater of kermanshah city with various tube bundle arrangements. in order to validate the numeric...

The momentum of light in a plasma and the transfer from to is calculated for uniform plane incident into plasma. At low irradiance, Minkowski Abraham expressions photon are shown be equivalent. We evaluate relativistic electron motion at high irradiance show that most transferred electrons associated with parallel propagation an corresponding reduced vector potential ao≈3.7 (reduced Iλ2≈2×1019 ...
