1. Semi-implicit Runge–Kutta schemes for the Navier–Stokes equations
Sammanfattning : .... LÄS MER
2. Accuracy and Convergence Studies of the Numerical Solution of Compressible Flow Problems
Sammanfattning : The numerical solution of compressible flow problems governed by the Navier-Stokes equations is considered. A finite volume method is used for the discretization in space. Different techniques to accelerate the convergence to a steady state are suggested, and the accuracy of the spatial difference operator is analyzed. LÄS MER
3. Two semi-implicit methods for solving the incompressible Navier-Stokes equations
Sammanfattning : .... LÄS MER
4. Transonic flow: large eddy simulation, numerical methods and subgrid modeling
Sammanfattning : Shock wave turbulent boundary layer interactions (SWTBLI) commonly arise in turbomachinery and aerospace applications and on the exterior of high speed aircrafts. In all these cases, SWTBLI can significantly change the flow and hence the physical load imposed by it. LÄS MER
5. Numerical Computations with Fundamental Solutions
Sammanfattning : Two solution strategies for large, sparse, and structured algebraic systems of equations are considered. The first strategy is to construct efficient preconditioners for iterative solvers. The second is to reduce the sparse algebraic system to a smaller, dense system of equations, which are called the boundary summation equations. LÄS MER
