A finite-difference lattice Boltzmann approach for gas microflows
G. P. Ghiroldi, L. Gibelli
Finite-difference Lattice Boltzmann (LB) models are proposed for simulating gas flows in devices with microscale geometries. The models employ the roots of half-range Gauss-Hermite…
A direct method for the Boltzmann equation based on a pseudo-spectral velocity space discretization
Gian Pietro Ghiroldi, Livio Gibelli
A deterministic method is proposed for solving the Boltzmann equation. The method employs a Galerkin discretization of the velocity space and adopts, as trial and test functions, t…
Solving the Boltzmann Equation on GPU
Aldo Frezzotti, Gian Pietro Ghiroldi, Livio Gibelli
We show how to accelerate the direct solution of the Boltzmann equation using Graphics Processing Units (GPUs). In order to fully exploit the computational power of the GPU, we cho…
Solving Kinetic Equations on GPUs I: Model Kinetic Equations
Aldo Frezzotti, Gian Pietro Ghiroldi, Livio Gibelli
We present an algorithm specifically tailored for solving kinetic equations onto GPUs. The efficiency of the algorithm is demonstrated by solving the one-dimensional shock wave str…
