An asymptotic-preserving adjoint unified gas kinetic scheme for sensitivity analysis
Yue Zhang, Junzhe Cao, Wenpei Long +1
High-dimensional sensitivity analysis and uncertainty quantification for multiscale gas dynamics, spanning the continuum to rarefied regimes, require computationally efficient and…
An Implicit Time-Domain Harmonic Balance Method for Radio-Frequency Capacitively Coupled Plasma Simulations
Yuze Zhu, Yufeng Wei, Yue Zhang +1
Fast and accurate fluid simulation of radio-frequency capacitively coupled plasmas (RF CCPs) is of great importance for the iterative design and parameter optimization of modern pl…
Unified Gas-Kinetic Scheme for Unsteady Multiscale Flows with Moving Boundaries
Yue Zhang, Wenpei Long, Junzhe Cao +1
Simulating multiscale flows with moving boundaries, such as hypersonic multi-body separation and flows in micro-electro-mechanical systems (MEMS), requires robust numerical methods…
A single-stage high-order compact gas-kinetic scheme in arbitrary Lagrangian-Eulerian formulation
Yue Zhang, Xing Ji, Yibing Chen +2
This study presents the development of a compact gas-kinetic scheme using an arbitrary Lagrangian-Eulerian (ALE) formulation for structured meshes. Unlike the Eulerian formulation,…
An implicit gas-kinetic scheme for internal and external flows
Yue Zhang, Xing Ji, Kun Xu
The gas-kinetic scheme(GKS) is a promising computational fluid dynamics (CFD) method for solving the Navier-Stokes equations. It is based on the analytical solution of the BGK equa…
An efficiency and memory-saving programming paradigm for the unified gas-kinetic scheme
Yue Zhang, Yufeng Wei, Wenpei Long +1
In recent years, non-equilibrium flows have gained significant attention in aerospace engineering and micro-electro-mechanical systems. The unified gas-kinetic scheme (UGKS) follow…
