Аннотация
Applicability limits of the particle-in-сell (PIC) method for the calculation of jet gasdynamic flows under conditions of pressure variations by four or five orders of magnitude are studied. Three approaches permitting one to determine real limits of the model adequacy from the side of low pressures are considered. Based on the analysis of the results, it is shown that the PIC method adequately operates in the pressure range of 5–105 Pa in spite of the fact that, formally, the PIC method can operate also at lower pressures.
