✦ Synopsis

The effect of swirl on heat transfer by axial and radial laminar jets impinging on a flat plate has been investigated numerically through the solution of Navier-Stokes and energy equations. Heat transfer is reduced substantially by the superposition of swirl on axial jets. Significant enhancement in heat transfer has been observed in the case of a radial jet with superimposed swirl on it. For a swirl number of unity, the heat transfer is enhanced by (77 %).

Numerical results are presented in graphical form for a range of parameters where multiple solutions may occur. These results provide valuable material for a further theoretical examination of multiplicity. It is also shown that in multiple cases the Danckwerts boundary conditions are consistent wit
