Investigation of Spontaneous Combustion of Hydrogen-Oxygen Mixture using DSMC Simulation

, 2014
Combustion has been widely studied in the literature, but very little work was focused on the microscopic level. In this paper, the DSMC method is applied to simulate the microscopic behavior of the spontaneous combustion of hydrogen ...

Analysis of Numerical Errors in the DSMC Method [PDF]

, 2020
. The direct simulation Monte Carlo (DSMC) method is one of the most popular numerical methods used to model rarefied gas environment flows. In order to predict the accuracy of a solution obtained by the DSMC method we have to be able to estimate its ...

Thermally Driven Atmospheric Escape: Transition from Diffusion-limited to Drag-off Escape

The Planetary Science Journal
We examine the transition from diffusion-limited to drag-off escape using a direct simulation Monte Carlo (DSMC) model developed to simulate planetary atmospheres, referred to as Harrah.

On Adaptive Fractional Dynamic Sliding Mode Control of Suspension System

Computation
This paper introduces a novel adaptive control method for suspension vehicle systems in response to road disturbances. The considered model is based on an active symmetry quarter car (SQC) fractional order suspension system (FOSS).
