Stagnation point heat transfer for jet impingement to a plane surface

Abstract

C -const, Eq. (2) CH = Stanton number, CH = h/p00V00Cp Cp = specific heat Di = local jet diameter = jet diameter = nozzle diameter = heat-transfer coefficient = nozzle-to-plate spacing = thermal conductivity = characteristic length, L = Vm /ft Prandtl number, Pr= Cpp/k = stagnation point heat-transfer flux, Eq. (1) = radial distance along surface = Reynolds number, ReD. = p00 V^D^^ -Reynolds number, Re^p^ V^L/p^ = Reynolds number, Rew.=p(X>Vco W^p^ -total temperature = wall temperature = potential flow velocity along surface = potential flow velocity normal to surface FQO = freestream velocity normal to surface Wj width of infinite two-dimensional jet ]8 = stagnation point velocity gradient, 0 = (d U/ dr) r=0 /iw = fluid viscosity at wall temperature jitoo = fluid viscosity at freestream temperature pw = fluid density at wall temperature p «, = fluid density at freestream temperature D h H k L Pr
