Abstract:With the theory of aerodynamics, the efficient gas wave condensation graph was established. To optimize the gas wave condensation graph and estimate the internal structure parameters of the device, the two-dimensional periodic boundary model was adapted and the ideal gas as the medium was used to numerical simulate the flow and temperature field of the efficient gas wave condensation separator. The thermodynamic model of condensing system was established and its thermodynamic properties were analyzed. At the same time, the experimental platform was built, and the main parameters of the device were studied. The experimental results shows: by using the shock wave to recycle the pressure energy of the high pressure admission, the pressure energy of the drying gas can be highly recovered. By recycling the cooling capacity of the drying gas and pre-cooling the next high pressure admission circulation, the lower condensation temperature can be obtained. The refrigeration efficiency of this device exists the single-valued optimal point. The internal expansion efficiency of efficient gas wave condensation is about 63% and the maximum of the drying gas pressure can be recovered to 90%, which decreases with the increase of the pressure ratio.
