A High-Order Semi-Lagrangian Finite Difference Method for Nonlinear Vlasov and BGK Models
Communications on Applied Mathematics and Computation - Tập 5 - Trang 170-198 - 2022
Linjin Li, Jingmei Qiu, Giovanni Russo
In this paper, we propose a new conservative high-order semi-Lagrangian finite difference (SLFD) method to solve linear advection equation and the nonlinear Vlasov and BGK models. The finite difference scheme has better computational flexibility by working with point values, especially when working with high-dimensional problems in an operator splitting setting. The reconstruction procedure in the...... hiện toàn bộ

A Unified Petrov–Galerkin Spectral Method and Fast Solver for Distributed-Order Partial Differential Equations
Communications on Applied Mathematics and Computation - Tập 3 - Trang 61-90 - 2020
Mehdi Samiee, Ehsan Kharazmi, Mark M. Meerschaert, Mohsen Zayernouri
Fractional calculus and fractional-order modeling provide effective tools for modeling and simulation of anomalous diffusion with power-law scalings. In complex multi-fractal anomalous transport phenomena, distributed-order partial differential equations appear as tractable mathematical models, where the underlying derivative orders are distributed over a range of values, hence taking into account...... hiện toàn bộ
A Blade Altering Toolbox for Automating Rotor Design Optimization
Communications on Applied Mathematics and Computation - - 2024
Akiva R. Wernick, Jen‐Ping Chen
AbstractThe Blade Altering Toolbox (BAT) described in this paper is a tool designed for fast reconstruction of an altered blade geometry for design optimization purposes. The BAT algorithm is capable of twisting a given rotor’s angle of attack and stretching the chord length along the span of the rotor. Several test cases were run using the BAT’s algorithm. The BAT...... hiện toàn bộ

Communications on Applied Mathematics and Computation - Tập 3 - Trang 123-135 - 2020
Xiao-Xia Guo, Hong-Xiao Wu
In this paper, we study the nonlinear matrix equation $$X-{A^{\rm{H}}}{\overline{X}}^{-1}A=Q$$ , where $$A,Q \in {{\mathbb {C}}}^{n\times n}$$ , Q is a Hermitian positive definite matrix and ...... hiện toàn bộ
Constructing a CDG Finite Element with Order Two Superconvergence on Rectangular Meshes
Communications on Applied Mathematics and Computation - - Trang 1-15 - 2023
Xiu Ye, Shangyou Zhang
A novel conforming discontinuous Galerkin (CDG) finite element method is introduced for Poisson equation on rectangular meshes. This CDG method with discontinuous $$P_k$$ ( $$k\geqslant 1$$ ) elements converges to the true...... hiện toàn bộ
