Влияние Конденсации На Размеры Сверхзвуковых Потоков

Abstract

The role of condensation on the shape and size of a supersonic argon stream flowing from a nozzle into a rarefied space is considered. It is shown that with the growth of cluster sizes, both the primary "traditional" supersonic jet and the external cluster flow formed when heavy clusters penetrate through the lateral compressed layers of the primary flow into the surrounding background gas increases. The type of correction factor in the well-known empirical formula proposed by Ashkenas and Sherman is found, taking into account which this formula can be used in conditions of clustered flows. The reasons for the impact of clusters on the gas dynamics of supersonic flow, conditions and limitations of such an effect are discussed.
