SUMMARYTwo-dimensional transient laminar incompressible o set jet is simulated numerically to gain insight into convective recirculation and ow processes induced by an o set jet. The behaviour of the jet with respect to o set ratio (OR) and Reynolds number (Re) are described in detail. The transient development of the velocity is simulated for various regions: recirculation, impingement and wall jet development. It is found that the reattachment length is dependent on both Re and OR for the range considered. Simulations are made to show the e ect of entrainment on recirculation eddy. A detailed study of u velocity decay is reported. The decay rate of horizontal velocity component (u) is linear in impingement region. It is found that at high OR, velocity decay depends on Re only. Velocity proÿle in the wall jet region shows good agreement with experimental as well as similarity solutions. It is found that the e ect of Re and OR are signiÿcant to bottom wall vorticity up to impingement region. Far downstream bottom wall vorticity is independent of OR.

SUMMARYAn attempt is made to ÿnd out the suitable entrainment and exit boundary conditions in laminar ow situations. Streamfunction vorticity formulation of the Navier-Stokes equations are solved by ADI method. Two-dimensional laminar plane wall jet ow is used to test di erent forms of the boundary conditions. Results are compared with the experimental and similarity solution and the proper boundary condition is suggested. The Kind 1 boundary condition is recommended. It consists of zero ÿrst derivative condition for velocity variable and for streamfunction equation, mixed derivative at the entrainment and exit boundaries.

“…They concluded that the thermal conductivity of the protruding heat source affects the maximum temperature to the extent of 40%. Kuyper et al [3] and Velusamy et al [4] studied buoyant turbulent flows in square and rectangular enclosures. Many investigators have presented experimental results for mixed convection turbulent flows in various geometries (see, for example, Carr et al [5], Huang et al [6]and Zang and Dutta [7]).…”
