Aerodynamic Drag Characteristics of Ultra-Low Orbit Satellites
Taking the 180~300 km ultra-low orbit satellite as the research object, the aerodynamic drag characteristics of the typical shapes were studied by using the direct simulation Monte Carlo (DSMC) method in the free molecular flow simulation method, which ...

Unsteady Flow Driven by the Counter-Flow Jets of High-Altitude Engine Based on DSMC Simulation
Counter-flow engines are often used for aircraft slowing or separating. In order to study the interaction between the counter-flow jets and free stream at high altitudes, the rarefied flow driven by two counter-flow jets and hypersonic free stream was ...

Investigation of concentration variation of the components of a three-component gas mixtures in the radial and axial direction of a gas centrifuge machine under “total reflux flow” conditions by using the DSMC method [PDF]
In this paper, using a new combinatory meshing technique in the axisymmetric coordinate, a MCC-DSMC solver is introduced. Using this solver, the flow and the concentration variation inside a centrifuge machine in a rigid body rotation mode with the DSMC ...
