摘要：

Heat transfer from an isothermal plate by a two-dimensional laminar incompressible offset jet is simulated numerically. The heat transfer characteristics of the jet with respect to offset ratio (OR), Reynolds number (Re) and Prandtl number (Pr) are reported in details. At low Pr, conduction mode of heat transfer is dominant in the region. The isotherm is studied inside the recirculation region as well as in the reattachment location. The thermal boundary layer thickness is reduced when Pr is increased. Nusselt number is calculated for different OR and wide range of Re and Pr = 0. 1, 1 and 100. The variation of the average Nusselt number with different parameters is also reported in details. (C) 2008 Elsevier Masson SAS. All rights reserved.
