The flow and heat transfer characteristics of an impinging laminar square jet through cross - flow have been investigated numerically by using the three - dimensional Navier - Stokes and energy equations in steady state. The simulations have been carried out for jet to cross - flow velocity ratios between 0.5 and 10 and for nozzle exit to plate distances between 1D and 6D, where D is the jet width. The complex nature of the flow field featuring a horseshoe vortex has been investigated. The calculated results show that the flow structure is strongly affected by the jet - to - plate distance. In addition, for jet - to - plate spacing of one jet width and for jet to cross - flow velocity ratios less than 2.5 an additional peak occurs at about three - dimensional downstream of the jet impingement point. For high jet to cross - flow ratios two horseshoe vortices form around the jet in the case of small jet - to - plate spacings.
