Experimental and Computational Modeling of Rarefaction Wave Eliminators Suitable for the BRL 2.44 m Shock Tube

Abstract

Three general types of rarefaction wave eliminators, RWEs (solid plate, vented plate, and lattice) were tested on a 1/48th scale model of the BRL 2.44 m shock tube. Pressures were monitored along the test section with piezoelectric transducers to determine effectiveness of the RWEs tested. All types were found to be equally effective in reducing the rarefactions but the lattice type was most difficult to use. The solid plate and vented plate RWEs would both be suitable for the 2.44 m shock tube. Predictions are produced using the NASA-Ames one-dimensional computer hydrocode. The hydrocode can be used effectively to model a RWE for the 2.44 m shock tube. Experimental and computational results are compared.
