DSMC: A Statistical Mechanics Perspective [PDF]
Abstract This paper presents a perspective in which Direct Simulation Monte Carlo (DSMC) is viewed not in its traditional role as an algorithm for solving the Boltzmann equation but as a numerical method for statistical mechanics. First, analytical techniques such as the collision virial and Green-Kubo relations, commonly used in ...

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.

Evaluation of Micronozzle Performance through DSMC, Navier-Stokes and Coupled DSMC/Navier-Stokes Approaches [PDF]
, 2009 Both the particle based Direct Simulation Monte Carlo (DSMC) method and a compressible Navier-Stokes based continuum method are used to investigate the flow inside micronozzles and to predict the performance of such devices. For the Navier-Stokes approach, both slip and no-slip boundary conditions are applied.

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 ...

Geometrically Non-Linear Vibration of a Cantilever Interacting with Rarefied Gas Flow
Cybernetics and Information Technologies, 2020 The work is devoted to study 2D pressure driven rarefied gas flow in a microchannel having an elastic obstacle. The elastic obstacle is clamped at the bottom channel wall and its length is half of the channel height.
