We discuss the kinetic representation of gases and the derivation of macroscopic equations governing the thermomechanical behavior of a dilute gas viewed at the macroscopic level as a continuous medium. We introduce an approach to kinetic theory where spatial distributions of the molecules are...

The relativistic shock layer problem was numerically analyzed by using two relativistic Boltzmann–kinetic equations. One is Marle model, and the other is Anderson–Witting model. As with Marle model, the temperature of the gain term was determined from its relation with the dynamic pressure...

Gas molecular motions around a laser opto-microengine are numerically simulated by direct simulation Monte Carlo (DSMC) method. We propose an opto-microengine that acts as a micro-actuator in which optical energy is supplied by a laser beam. The opto-microengine is rotated by molecular gas...
