Abstract :

The phenomenon of heat transfer in a complex movement of the currents that in addition to having free movement caused by an external source of a stream, In different industries is remarkable. In most industrial problems we deal with a heat transfer in square or rectangular ducts, Dealing. .square and rectangular shape can increase heat transfer surface than spherical shape and we can save money with producing rectangular ducts. .cooling in most electronic equipment happened with complex flow and various fluids with scribe this phenomenon and knows that how to using effect. We can benefit for cooling and loosing temperature of flow convection canals for example square and rectangular canals in various industries. In this paper, first we consider a channel with a rectangular cross-section and we apply different boundary condition in this canal. At last we discuss heat transfer under immature velocity and temperature condition with viscosity effect that related to temperature.


Keywords :

Complex flow, Flow convection, Viscosity, Immature profile
