    A Parallel Performance Study of the High-order Compact Direct Flux Reconstruction Method for Conservation Laws on Maya Cluster 

    Wang, Lai; Yu, Meilin; Gobbert, Matthias K. (2017)
    The compact direct flux reconstruction method (CDFR) for conservation laws utilizes techniques from compact finite difference methods to directly approximate spatial derivatives of fluxes within standard elements. The CDFR ...

    A Preconditioned Flux Reconstruction/Correction Procedure via Reconstruction Formulation for Unsteady Low Mach Number Flows on Dynamic Unstructured Meshes 

    Wang, Lai; Yu, Meilin (AIAA SciTech Forum, 2017)
    Preconditioning methods can signicantly decrease the condition number of the linear system resulted from the discretization of compressible Navier-Stokes equations at low Mach numbers by replacing the physical acoustic ...

    A High-Order Dual-Time Stepping FR/CPR Method for Unsteady Incompressible Navier-Stokes Equations on Unstructured Moving Grids 

    Wang, Lai; Yu, Meilin (AIAA SciTech Forum, 2016)
    A high-order accurate flux reconstruction/correction procedure via reconstruction (FR/CPR) method is developed to solve incompressible Navier-Stokes equations on unstructured moving grids. An artificial compressibility ...

    On the parallel implementation and performance study of high-order Rosenbrock-type implicit Runge-Kutta methods for the FR/CPR solutions of the Navier-Stokes equations 

    Wang, Lai; Yu, Meilin (AIAA SciTech Forum, 2018)
    The Rosenbrock-type implicit Runge-Kutta (ROIRK) methods only require one Jaco-bian matrix evaluation per time step rather than per stage as other types of implicit Runge-Kutta (IRK) methods need. This feature makes ROIRK ...

    An Implicit High-Order Preconditioned Flux Reconstruction Method for Low-Mach-Number Flow Simulation with Dynamic Meshes 

    Wang, Lai; Yu, Meilin (2019-03-15)
    A fully implicit high-order preconditioned ux reconstruction/correction procedure via reconstruction (FR/CPR) method is developed to solve the compressible Navier{Stokes equations at low Mach numbers. A dual-time stepping ...

    A comparative study of implicit Jacobian-free Rosenbrock-Wanner, ESDIRK and BDF methods for unsteady flow simulation with high-order flux reconstruction formulations 

    Wang, Lai; Yu, Meilin (2019-04-09)
    We conduct a comparative study of the Jacobian-free linearly implicit Rosenbrock-Wanner (ROW) methods, the explicit rst stage, singly diagonally implicit Runge-Kutta (ESDIRK) methods, and the second-order backward ...

    Towards High-order Accurate Numerical Simulation of Unsteady Flow Physics over Domains with Large Deformation 

    Yu, Meilin; Liu, Kan; Wang, Lai (AIAA, 2019)
    This paper presents the development of a high-order flux reconstruction (FR) formulation for unsteady flow simulation with dynamic grid algorithms. Specifically, the high-order FR formulation for the Navier-Stokes equations ...

    An implicit P-multigrid flux reconstruction method for simulation of locally preconditioned unsteady Navier–Stokes equations at low Mach numbers 

    Wang, Lai; Yu, Meilin (2019-08)
    We develop a P-multigrid solver to simulate locally preconditioned unsteady compressible Navier–Stokes equations at low Mach numbers with implicit high-order methods. Specifically, the high-order flux reconstruction/correction ...

    Computational Study of Flapping Wing Response to Vertical Gusts at Low Reynolds Numbers 

    Poudel, Naresh; Wang, Lai; Yu, Meilin (American Institute of Aeronautics and Astronautics, 2020-01-05)
    This work presents a computational study of an oscillating NACA0012 airfoil’s response to vertical gusts at low Reynolds numbers. The gust is created by a cross-flow ducted floor jet and its interaction with a freestream ...

    A dynamically load-balanced parallel p-adaptive implicit high-order flux reconstruction method for under-resolved turbulence simulation 

    Wang, Lai; Gobbert, Matthias K.; Yu, Meilin (2019-10-08)
    We present a dynamically load-balanced parallel p-adaptive implicit high-order flux reconstruction method for under-resolved turbulence simulation. The high-order explicit first stage, singly diagonal implicit Runge-Kutta ...
