Data which illustrate the effects of hole spacing on spatially-resolved heat transfer from an array of jets impinging on a flat plate are presented. Considered are Reynolds numbers ranging from 8200 to 30,500, and Mach numbers from 0.1 to 0.6. The spacing of the holes used to produce the impinging j
The effects of the nozzle contraction ratio on the flow and heat transfer characteristics of an orifice impinging jet were investigated in this experiment. The nozzle diameter was d o = 10.0 mm = const., and the contraction area ratio CR = (d o /d i ) 2 , where d i is the inner pipe diameter was var
## Abstract A theoretical and experimental investigation of a water jet impinging on a melting solid surface has been carried out. Ice, octane, __p__βxylene, and olive oil served as the meltable solid materials, comprising a Prandtl number range of 5 to 2 800. An available laminar stagnation flow m
