对超声电喷推进微细驻波进行了研究,试验观测了微细驻波形成形态,并在不同频率下对比分析了微细驻波波长的理论值和试验值;同时分析了不同推进剂条件下,振动频率对微细驻波波长和形成驻波所需振幅的影响规律。结果表明:不同频率下,形成微细驻波波长的理论值和试验值具有较好的一致性;微细驻波的波长和振幅随着振动频率的增大而减小,同时推进剂的粘度越大,形成微细驻波所需的振幅也越大。
The research on the formation of fine standing wave was carried out. The theoretical value and the experimental value of the wavelength of the fine standing wave were compared and analyzed under different frequencies. At the same time, the effects of different propellants on the vibration The effect of the frequency on the amplitude of the fine standing wave and the amplitude required for the formation of a standing wave. The results show that the theoretical value and the experimental value of the formation of the fine standing wavelength are in good agreement at different frequencies. The wavelength and amplitude of the fine standing wave decrease with the increase of the vibration frequency, and the viscosity of the propellant is larger , The greater the amplitude required to form a fine standing wave.
