FLOW TABLES FOR AIR (GAMMA = 1.4) PASSING AN ABRUPT AREA INCREASE OBLIQUE TO THE FLOW DIRECTION,

Abstract

Tabulated values are presented for the flow conditions before and after a step increase in area oblique to the flow direction. This condition may arise with a swirl flow in an annulus, or flow between parallel planes which extend to in finity in the direction parallel to the step. The tables apply to a compressible fluid with a specific-heat ratio of 1.4. The flow is assumed adiabatic and without wall friction. Downstream conditions apply at a location sufficiently far downstream such that uniform flow has been reestablished. Input variables considered are area ratio, Mach number component normal to the abrupt area change, and the angle between the flow direction and the normal. Calculated quantities are the absolute up-and downstream Mach numbers, the angle between downstream flow and the normal, static pressure ratio, and total pressure ratio. The method of calculation is described. (Author)
