Numerical Simulation of the Blast Impact Problem Using the Direct Simulation Monte Carlo (dsmc) Method
A particle approach using the Direct Simulation Monte Carlo (DSMC) method is used to solve the problem of blast impact with structures. A novel approach to model the solid boundary condition for particle methods is presented. The solver is validated against an analytical solution of the Riemann shocktube problem and against experiments on interaction of a planar shock with a square cavity. Blas...
متن کاملMonte Carlo Radiative Heat Transfer Simulation on a Reconfigurable Computer
Recently, the appearance of very large (3 – 10M gate) FPGAs with embedded arithmetic units has opened the door to the possibility of floating point computation on these devices. While previous researchers have described peak performance or kernel matrix operations, there is as yet relatively little experience with mapping an application-specific floating point loop onto FPGAs. In this work, we ...
متن کاملAn improved BGK-type collision-term model for Direct Simulation Monte Carlo (DSMC) methods
The BGK and BGKC (Bhatnagar, Gross, Krook, and Cercignani) collision-term models for the Boltzmann equation are compared to the more rigorous variable-hard-sphere (VHS) collision-term model of Bird. The BGKC model is based on the well-known BGK model but uses an ellipsoidal statistical (ES) distribution instead of a Maxwellian distribution so as to incorporate both viscous effects and heat cond...
متن کاملNonideal gas flow and heat transfer in micro- and nanochannels using the direct simulation Monte Carlo method.
Subsonic nonideal gas flow and heat transfer in micro- and nanochannels for different Knudsen numbers are investigated numerically using the direct simulation Monte Carlo method modified with a consistent Boltzmann algorithm. The van der Waals equation is used as the equation of state. The collision rate is also modified based on the Enskog theory for dense gas. It is shown that the nonideal ga...
متن کاملInvestigation of Quantum and Classical Models for Molecular Relaxation Using the Direct Simulation Monte Carlo (dsmc) Method
It is widely known that losses due to viscous, thermal and molecular relaxation play an important role in sound propagation. Traditionally, acoustics is concerned with the treatment of the fluid as a (linear) continuum using macroscopic quantities such as velocity and pressure as dependent variables. However, the continuum model has its limitations and the model breaks down for Knudsen numbers ...
