Abstract:

An investigation was made concerning the effect of inlet velocity on the pressure recovery efficiency of a subsonic conical diffuser with and without a ring-airfoil installed. Three diffusers and two ring-airfoils were tested over a range of inlet Mach Number 0.30 or M or 0.70. The conclusions reached for diffusers with and without ring-airfoils are 1 the compressibility Mach Number effect is small compared to the Scaling Reynolds Number effect, 2 there is an optimum Mach Number for each diffuser at which the pressure recovery efficiency is a maximum, and 3 pressure recovery efficiency variation with respect to Mach Number ranged from 3 to 7 over the range .25 or M or .70. Experimental results are presented for conical diffusers with and without a ring-airfoil mounted. Author
