Numerical Investigation of Effect of Structural Parameters on the Performance of a Combustion-Driven Sparkjet Actuator

With the aim of increasing momentum jet and obtaining better environmental adaptability, this study designs a new type actuator combining sparkjet combustion-driven actuator. Numerical simulation shows that has higher velocity mass rate compared to when length orifice diameter are 6.5 mm 1.3 mm, respectively, while saturation work frequency is almost same. A parameter as volume increases, pressure, velocity, increase. By contrast, decreases. Moreover, decreases, peak temperature, pressure increase, whereas flow decrease.
