Abstract: Flow and heat transfer characteristics of interaction of a laminar plane offset jet with coflowing wall jet are studied at various Richardson number (Ri). The temperature of offset jet at inlet is higher than that of wall jet inlet temperature. The temperature of horizontal wall and wall jet inlet temperature are same as that of ambient temperature. The temperature of heated offset jet is varied to alter the Grashof number (Gr). The velocities of the two jets are taken equal. Study is carried out for Ri ranging from 0.0028 to 0.875 by taking Gr 1000, 10000 and 35000 for Reynolds number 200, 400 and 600. PISO algorithm based on finite volume method (FVM) is used. Power law scheme is considered for the discretization of convective terms. Boussinesq approximation is used to take into account variation in density in the buoyancy term. It is observed that mixing and heat transfer between the offset jet and wall jet increases with increase in Richardson number.
