Abstract : Discharge coefficients of axisymmetric contoured nozzles under steady, critical flow conditions were studied theoretically. In the analysis, axisymmetric compressible laminar boundary layer flow was considered for a perfect gas with Prandtl number unity and viscosity proportional to temperature. The wall was assumed to be adiabatic. Solutions to the equations describing the discharge coefficient were obtained analytically in closed form when the pressure-gradient parameter (Beta) was infinite. Numerical computations were carried out for two other cases, Beta = 2 and Beta = 1. (Author)
