Thermodynamic characteristics of a blunt, two-dimensional resonance tube
Abstract
An experimental investigation of a simple, two-dimensional resonance tube has been conducted. The leading edge of the resonance tube was blunt in order to simulate the geometric configuration of proposed rocket ignition systems. Thermodynamic characteristics of the fluid near the endwall were determined for a range of jet stagnation pressures, nozzle-resonance tube separation distances, and resonance tube lengths. Strong resonance, as indicated by high endwall temperatures was obtained for both supercritical and subcritical jet pressure ratios. The latter results are of particular significance for the design of resonance tube ignition systems.
