Modelling and Simulation of Heterogeneous Reactions with Statistical Particle Methods
Wladimir Reschke, Marcel Pfeiffer, Stefanos Fasoulas
Estimating the heat loads on re-entry vehicles is a crucial part of preparing for atmospheric re-entry manoeuvres. Re-entry flows at high altitudes are in the rarefied regime and a…
A Load Balance Strategy for Hybrid Particle-Mesh Methods
P. Ortwein, T. Binder, S. Copplestone +5
We present a load balancing strategy for hybrid particle-mesh methods that is based on domain decomposition and element-local time measurement. This new strategy is compared to our…
Load balancing strategies for the DSMC simulation of hypersonic flows using HPC
T. Binder, S. Copplestone, A. Mirza +6
In the context of the validation of PICLas, a kinetic particle suite for the simulation of rarefied, non-equilibrium plasma flows, the biased hypersonic nitrogen flow around a blun…
Extending the Particle ESBGK Method to Diatomic Molecules including Quantized Vibrational Energies
Marcel Pfeiffer
The particle-based ellipsoidal statistical Bhatnagar-Gross-Krook (ESBGK) model is extended to diatomic molecules and compared with the Direct Simulation Monte Carlo (DSMC) method.…
Particle-based fluid dynamics: comparison of different BGK models and DSMC for hypersonic flows
M. Pfeiffer
The Bhatnagar-Gross-Krook (BGK) model as well as its extensions (ellipsoidal statistical BGK, Shakhov BGK, unified BGK) are used in particle-based fluid dynamics and compared with…
