OpenFOAM has an extensive range of features to solve anything from complex fluid. The extra environment variable profile_foam can be used to specify a particular version of OpenFOAM should be used instead of searching through the list and makes it easier to write a corresponding alias. The direct simulation Monte Carlo (DSMC) technique is a stochastic particle-based method for simulating dilute gas flow problems. The distributions of velocity field and temperature around the capsule were calculated. A main handicap of DSMC method is the requirement of a large number of samples to reduce the statistical scatter in simulation of low-speed flows. According to the experiments performed [1], it is seen that applying a potential to the nozzle leads The distributions of velocity field and The rarefied gas has the Knudsen number with 0.03.
