Undergraduate studies are carried out in the advanced laboratory to examine the supersonic flow from an axisymmetric converging-diverging nozzle. Flow is initiated by the rupture of a diaphragm and exits from a small nozzle (with a 0.95 cm exit diameter) into standard atmospheric conditions from a one gallon (3.875 liter) tank. Compressible flow simulations are carried out for the nozzle and comparisons are made to experiments based on high-speed video shadowgraph imaging and dual-beam interferometry. The multifaceted approach based on simulation and experiments exploits the distinct strengths of the different methods to provide a more comprehensive description of the nozzle flow than is achievable by the individual approaches.
