摘要：

Choked capillary flow is described by an isothermal, locally developed flow model while flow in the supersonic free jet originating at the capillary exit is assumed isentropic in order to calculate volumetric gas flow through the capillary and the terminal velocity of particles suspended in the expanding gas. The results are compared to experimental data and found to agree within 2 to 3%. The principal cause of error is believed to be the failure of the capillary flow model near the capillary exit. © 1979.
