A Theoretical Analysis of Jet Deflection from Plane and Axisymmetric Curved Obstacles.

Abstract

A class of analytical and numerical solutions to the problem of inviscid-jet deflection from plane and axisymmetric concave surfaces are presented. The methods of solution for the two-dimensional cases includes a novel method developed in the present investigation, as well as those due to Levi-Civita and Riemann and Hilbert. These methods have provided indirect solutions for the shape of the curved solid boundary in terms of a given jet-dpearture and jet-deflection angle. The axisymmetric cases, namely, the deflection of axisymmetric jets from hemispherical thrust reversers are solved directly through the use of the finite element method and a novel iteration scheme. The real-fluid effects on the jet deflection are estimated by comparing the results with those obtained experimentally. (Modified author abstract)
