High-Order Shock-Fitting and front-tracking Methods for Numerical Simulation of Shock-Disturbance Interactions
High-order methods that can resolve interactions of flow-disturbances with shock waves are critical for reliable numerical simulation of strong-shock and turbulence interaction problems. Such problems are not well understood due to limitations of numerical methods. Most of the popular shock-capturing methods are inherently dissipative and may incur numerical oscillations near the shock. Present...
متن کاملHigh-Order Shock-Fitting Method for Hypersonic Flow with Graphite Ablation and Boundary Layer Stability
A high-order shock-fitting method with thermochemcial nonequilibrium and finite rate boundary conditions for graphite ablation is presented. The method is suitable for direct numerical simulation of boundary layer stability with graphite ablation. Validation with three computational data sets and one set of experimental data is shown. Stability results of the method for a 7 half angle blunt con...
متن کامل3 Shock Capturing Methods
8 were performed by Mark Sussman, see ref 29], 30]. The algorithm is based on the level set method and is quite simple to implement. It should be stressed that no special work is needed at pinchoo, merging, development of kinks, etc. and the algorithm is very easy to implement on a xed, uniform grid. All these gures should be read left to right, top to bottom. Figure 1 shows the evolution of a ...
متن کاملNumerical Simulations of Strong Shock and Disturbance Interactions Using High-Order Shock-Fitting Algorithms
High order methods that can solve flows involving interactions of flow-disturbances with shock waves are critical for reliable numerical simulation of strong-shock and turbulence interaction problems. Such problems are not well understood due to limitations of numerical methods. For numerical simulation of compressible flows, shock capturing schemes have been the most popular choice. However, m...
متن کاملHigh-order shock-fitting methods for hypersonic flow with chemical and thermal nonequilibrium
Computer simulations have been an effective tool to study transient flow processes in hypersonic flow and have been complementing experimental and theoretical studies to better understand the flow transition process. There have been lots of efforts in code development for high order simulation of nonequilibrium flow but most of the methods are based on shock capturing ideodology. Shock capturin...
