A fast Fourier spectral method for the homogeneous Boltzmann equation with non-cutoff collision kernels
Jingwei Hu, Kunlun Qi
We introduce a fast Fourier spectral method for the spatially homogeneous Boltzmann equation with non-cutoff collision kernels. Such kernels contain non-integrable singularity in t…
Quantification of thermally-driven flows in microsystems using Boltzmann equation in deterministic and stochastic contexts
Shashank Jaiswal, Aaron Pikus, Andrew Strongrich +3
When the flow is sufficiently rarefied, a temperature gradient, for example, between two walls separated by a few mean free paths, induces a gas flow---an observation attributed to…
A discontinuous Galerkin fast spectral method for multi-species full Boltzmann on streaming multi-processors
Shashank Jaiswal, Jingwei Hu, Julien K. Brillon +1
When the molecules of a gaseous system are far apart, say in microscale gas flows where the surface to volume ratio is high and hence the surface forces dominant, the molecule-surf…
A discontinuous Galerkin fast spectral method for the multi-species Boltzmann equation
Shashank Jaiswal, Alina A. Alexeenko, Jingwei Hu
We introduce a fast Fourier spectral method for the multi-species Boltzmann collision operator. The method retains the riveting properties of the single-species fast spectral metho…
A Discontinuous Galerkin Fast Spectral Method for the Full Boltzmann Equation with General Collision Kernels
Shashank Jaiswal, Alina A. Alexeenko, Jingwei Hu
The Boltzmann equation, an integro-differential equation for the molecular distribution function in the physical and velocity phase space, governs the fluid flow behavior at a wide…
