通过对现有的削弱气波机接受管内激波能量的方法进行一一比较后 ,提出了一种新的削弱反射激波能量的方法 ,即利用一种新型的填料———“多孔填料”使之与反射激波相互作用 ,削弱其能量 ,达到提高制冷效率的目的。通过实验对这种方法的可行性进行了验证 ,并对现象进行了简单的理论分析。
By comparing the existing methods of attenuating the shock wave energy in the tube, a new method to weaken the energy of the reflected shock wave is proposed. That is, a new type of filler, “porous filler” So that the interaction with the reflected shock wave, weaken its energy, to achieve the purpose of improving refrigeration efficiency. The feasibility of this method is verified through experiments, and a simple theoretical analysis of the phenomenon is carried out.
