The development of detached shock waves in gas-solid suspension flow
Abstract
The development of detached shock waves ahead of wedges of 20 and 180 angle placed in a gas-solid flow shock tube has been observed optically using models of different geometries. The behaviour of the detachment distance and the distance between the triple point and the shoulder of the wedge has been investigated for various values of solids loading ratio and diaphragm pressure ratio. An on-line computer technique for the measurement of pressure and air and solid flow rates has been developed. The static pressure upstream and downstream of the leading edge of the wedge has been determined and found to depend on the solids loading ratio, the diaphragm pressure ratio and the wedge geometries.
