Journal of Fluid Science and Technology, 2016 A micro size particle behavior considering thermophoretic and drag forces are simulated by using direct simulation Monte Carlo (DSMC) method. The computation time is too high to compute the micro particle movement by conventional DSMC method because the ...

Numerical simulation of 3-D flow around sounding rocket in the lower thermosphere [PDF]
Annales Geophysicae, 2006 Numerical simulations using the Direct Simulation Monte Carlo (DSMC) method are known to be useful for analyses of aerodynamic effects on in-situ rocket measurements in the lower thermosphere, but the DSMC analysis of a spin modulation caused by an ...

A hybrid sliding mode control based on a nonlinear PID surface for nonlinear chemical processes
Engineering Science and Technology, an International Journal, 2023 This work formulated and synthesized a hybrid control framework based on sliding mode control and internal model concepts. The resulting design conducts a Dynamic Sliding Mode Control (DSMC) approach based on a Nonlinear PID (NPID) sliding surface.

Transient Macroscopic Chemistry in the DSMC Method [PDF]
AIP Conference Proceedings, 2008 In the Direct Simulation Monte Carlo method, a combination of statistical and deterministic procedures applied to a finite number of `simulator' particles are used to model rarefied gas-kinetic processes. Traditionally, chemical reactions are modelled using information from specific colliding particle pairs.

Unsteady Flow Driven by the Counter-Flow Jets of High-Altitude Engine Based on DSMC Simulation
气体物理, 2023 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 ...

Stochastic DSMC method for dense bubbly flows: Methodology
Chemical Engineering Science, 2018 A stochastic Direct Simulation Monte Carlo (DSMC) method has been extended for handling bubble-bubble and bubble-wall collisions. Bubbly flows are generally characterized by highly correlated velocities due to presence of the surrounding liquid. The DSMC method has been improved to account for these kind of correlated collisions along with a treatment ...
