Abstract

Studies were conducted on vortex flow generated within two right circular cylinders by injecting air through longitudinal vanes forming the chamber. The length to diameter ratios were 0.107 and 0.50. Experimental end wall static pressure distributions, some total pressures, and total temperature data are presented. The most significant finding was the large radial variations in the total temperature; this is related to the Ranque-Hilsch effect. Also discussed is the relationship between the static wall pressures and the effective velocities in the vortex.
