DSMC Calculations for The Delta Wing
1991In this study, a general three-dimensional direct simulation Monte Carlo (DSMC) program (developed by G. A. Bird) is used. The molecular collisions are modeled using the variable hard sphere (YHS) molecular model which treats the molecules as hard spheres as far as the scattering angle distribution is concerned, but the collision cross section depends ...

A new reaching law for DSMC systems with constraints
2016 21st International Conference on Methods and Models in Automation and Robotics (MMAR), 2016In this paper, a new reaching law is proposed and applied to synthesize a discrete time sliding mode control strategy. The strategy ensures at least asymptotic convergence of the state to a layer around the switching plane and guarantees an upper bounded convergence rate.

On the Time Step Error of the DSMC
AIP Conference Proceedings, 2003The time step truncation error of the DSMC is examined numerically. Contrary to the claim of [S.V. Bogomolov, U.S.S.R. Comput. Math. Math. Phys., Vol. 28, 79 (1988)] and in agreement with that of [T. Ohwada, J. Compt. Phys., Vol. 139, 1 (1998)], it is demonstrated that the error of the conventional DSMC per time step Δt is not O(Δt3) but O(Δt2 ...

A Hybrid Method that Interpolates Between DSMC and CFD
44th AIAA Aerospace Sciences Meeting and Exhibit, 2006For small Knudsen number, simulation of rarefied gas dynamics by the DSMC method becomes computationally intractable because of the large collision rate. To overcome this problem we have developed a hybrid simulation method, combining DSMC and a fluid dynamic description in a single seamless method.

Role of the Data and Safety Monitoring Committee (DSMC)
Statistics in Medicine, 2002AbstractThe Data and Safety Monitoring Committee (DSMC) is a committee independent of both the Steering Committee (SC) and any sponsor. It advises these bodies on continuation or stopping based upon safety and efficacy considerations. The primary objective is to assure safety for the patients in the trial.
