Experiments and Analyses on Shock Waves Propagating through a Gas-Particle Mixture

Numerical Simulation of Shock Wave Propagation n a Mixture of a Gas and Solid Particles

“…The flow in the shock wave (SW) propagating through such a mixture was described in many papers (see, e.g., [1,[9][10][11][12]). We assume that a quiescent mixture characterized by undisturbed flow parameters (ρ 10 , ρ 20 , u 10 = u 20 = 0, e 10 , e 20 , and p 0 ) is located in front of the SW.…”

Numerical Analysis of Dusty-Gas Flows

“…Many researchers worked on the subject from many different aspects of the problem in T. SAITO 1970s and 1980s. The shock wave propagation in a dusty gas is studied experimentally by the use of vertical shock tubes [12,14,18]. While various analytical and numerical techniques were developed to study how the shock wave structure changes with time in the dusty-gas shock tube.…”

On the method of indirectly measuring gas and particulate phase velocities in shock induced dusty-gas flows

“…For example, a flat-topped shock wave moving initially in a gaseous medium would undergo complicated wave reflection and refraction processes on entering and traversing a dusty gas (Miura and Glass 1983), and these processes would alter the shock wave's speed and structure towards the final stationary state (with a partly or fully dispersed structure). These events also occur when a shock wave is suddenly produced in a dusty-gas shock tube by the breaking of a diaphragm between the high and low pressure chambers (Outa et al 1976;Miura and Glass 1982;Sommerfeld and Gronig 1983;Sommerfeld 1985), and also when a shock wave is produced in front of a piston which is set in impulsive motion to a constant velocity (Miura and Glass 1985). A shock wave typically needs to travel a number of meters in a dusty gas (in a constant area duct) before it develops a structure which can be considered stationary.…”
