An investigation was conducted to accelerate solid and liquid particles in single and two stage nozzles with air and helium as the carrier gas in the primary nozzle. Methods were developed for injection and the particles were accelerated to supersonic air and helium velocities. Schlieren and light scattering systems were used to observe the shock waves in the flows and the liquid and solid particle streams discharging from the turning vanes and the nozzles. Laser doppler velocimeter technique was utilized to measure the mean velocity and the turbulence level of the liquid and solid particles in a supersonic air flows. Modified author abstract
