Laminar Forced Convection Modeling of Isothermal Rectangular Plates

چکیده
A composite model for area-average Nusselt number for forced, laminar ow parallel to a nite, isothermal rectangular plate for a wide range of Reynolds numbers is proposed. The correlation equation is based on the superposition of the dimensionless shape factor and a modi ed laminar ow boundary-layer asymptote with an empirically determined interpolation parameter. The Nusselt and Reynolds numbers and the dimensionless shape factor are based on either the rectangle side dimension parallel to the ow direction or the square root of the heat transfer area. The proposed correlation equationsare applicable to rectangles with side dimensionratios in a range from 1 to 10. Extensive numerical results were used to nd the optimal values of the interpolation parameter to provide close agreement between the correlation equation predictions and the numerical values.

A numerical study is carried out to investigate the laminar forced convection heat transfer from a circular cylinder. The fluid is assumed to be incompressible, the Reynolds number ranged from 0.1 to 1000, and the Prandtl number was equal to 0.7. The range of study includes heat transfer in creeping flow (Re40). The equations were discretized by a control-volume-based finite difference techniqu...
