Influences of structural and operating parameters on performance of self-excited pulse jet device
摘要
Abstract
In order to study the influences of structural and operating parameters on the performance of self-excited pulse jet device, a large number of experiments on the self-excited pulse jet device are performed by use of the self-developed test system. The influences of change of lower-nozzle diameter, cavity length and working pressure on the hitting power of the pulse jet and pulse effect are analyzed under the upper-nozzle diameter of 8 mm and the cavity diameter of 120 mm. The experimental results show that different lower-nozzle diameters, cavity lengths and working pressures have different influences on the hitting power of the pulse jet. Each lower-nozzle diameter has the optimal ranges of cavity length and working pressure for the best pulse effects. The smaller the cavity length, the better the pulse effects.关键词
