The DESIGN AND ANALYSIS OF SHOCK TUBE

Abstract

Topology optimization of shock tube involves the design modification of a conventional shock tube based on pressure and area ratios in order to achieve supersonic Mach number. A conventional shock tube consist of two sections namely the driver and the driven section. The interface between the two sections is said to be “DIAPHRAGM”. The driven and the driver ections are filled with atmospheric air and helium respectively under predominant condition. The three phases to achieve supersonic Mac number:
1. Dividing the driven section into number of sections.
2. Varying the cross section of the shock tube.
3. Changing the medium of the flow inside shock tube.
Pressure transducers could be used to measure the aerodynamic parameters in terms of pressure
by which other flow properties such as velocity and Mach number could be calculated. The
calculations are made mathematically and its optimization is done through simulation CFD.
