Experimental Research of Wave Resistance Resonance for Rough-Wall Planar Channels
We experimentally confirmed the effect when the wave resistance of relief-wall planar channels, generated while the walls are streamlined by a supersonic gas flow, reaches the extreme values. The experiments were conducted on a differential setup by comparing the tests of planar and round sonic nozzles. The results of the experiment justified the developed method of calculating the wave resistance of the planar channel with saw-tooth wall relief.
