Numerical simulation of flow over vacuum gauge using of direct simulation Monte-Carlo method

Upper atmosphere probe is under the consideration. Method of atmosphere parameters treatment of density data received by vacuum gauge located behind the cellular shield is constructed. Molecules interaction with cellular shield as with semipermeable membrane simplified algorithm was proposed within the framework of direct simulation Monte-Carlo method (DSMC). Flow over the probe numerical simulation was done for the purpose to get connection between probe data and undisturbed atmosphere parameters.
