Moment Methods for the 3D Radiative Transfer Equation Based on -Divergences
Michael R. A. Abdelmalik, Zhenning Cai, Teddy Pichard
The method of moments is widely used for the reduction of kinetic equations into fluid models. It consists in extracting the moments of the kinetic equation with respect to a veloc…
Regularization of Complex Langevin Method
Zhenning Cai, Yang Kuang, Hong Kiat Tan
The complex Langevin method, a numerical method used to compute the ensemble average with a complex partition function, often suffers from runaway instability. We study the regular…
Accurate and efficient calculation of photoionization in streamer discharges using fast multipole method
Bo Lin, Chijie Zhuang, Zhenning Cai +2
This paper focuses on the three-dimensional simulation of the photoionization in streamer discharges, and provides a general framework to efficiently and accurately calculate the p…
Burnett Spectral Method for High-Speed Rarefied Gas Flows
Zhicheng Hu, Zhenning Cai
We introduce a numerical solver for the spatially inhomogeneous Boltzmann equation using the Burnett spectral method. The modelling and discretization of the collision operator are…
An efficient and accurate MPI based parallel simulator for streamer discharges in three dimensions
Bo Lin, Chijie Zhuang, Zhenning Cai +2
In this paper, we propose an efficient and accurate message-passing interface (MPI)-based parallel simulator for streamer discharges in three dimensions using the fluid model. Firs…
Burnett Spectral Method for the Spatially Homogeneous Boltzmann Equation
Zhenning Cai, Yuwei Fan, Yanli Wang
We develop a spectral method for the spatially homogeneous Boltzmann equation using Burnett polynomials in the basis functions. Using the sparsity of the coefficients in the expans…
