Conjugate Mixed convection with Surface Radiation in an Inclined Channel with Protruding Heat Sources

Numerical solution for mixed convection combined with surface radiation in an inclined channel containing three protruding heat sourcesis investigated in this article. This combinations present printed circuit boards in electrical equipments. Air is assumed to be the working fluid which is laminar, steady, incompressible and thermally and hydrodynamicaly developing. Governing equations are discretized using the F.V. method in an staggered domain and simple algorithm is used to couple velocity and a pressure. Numerical results presented for temperature and velocity contribution and maximum temperature that occur in chips for different valuesof fan velocity as Reynolds number 15CkRe<1400 and heat generated in chips as Grashof number 1
