A Multi-domain Spectral Method for Supersonic Reactive Flows
نویسندگان
چکیده
This paper has a dual purpose: it presents a multidomain Chebyshev method for the solution of the two-dimensional reactive compressible Navier-Stokes equations, and it reports the results of the application of this code to the numerical simulations of high Mach number reactive ows in recessed cavity. The computational method utilizes newly derived interface boundary conditions as well as an adaptive ltering technique to stabilize the computations. The results of the simulations are relevant to recessed cavity ameholders.

HIGH ORDER ACCURACY METHODS FOR PDEs with SHOCKS and UNCERTAINTIES
The aim of t his project is the construction of efficient high fidelity schemes for systems of PDEs that contain shock waves. We advocate here the Discontinuous collocation method, i.e. multi-domain spe method with stable and conservative penalty interface conditions. In this work. the previously developed methodology is generalized to inhomogeneous grid to simulate the two dimensional superson...
متن کاملHigh-Order Methods for the Numerical Simulation of Vortical and Turbulent Flows Spectral methods for compressible reactive flows
High order simulations are necessary in order to capture fine details in resolving supersonic reactive flows. However, high Mach number compressible flows feature sharp gradients and discontinuities, which present a challenge to successful simulations using high order methods. Spectral methods have proven a powerful tool in simulation of incompressible turbulent flows, and recent advances allow...
متن کاملEvaluation of Roe s Method with Different Limiters in Supersonic 2-D and Axisymmetric Flows
2-D and axisymmetric Navier-Stokes equations are solved using Reiman-Roe solver with different limiters for second-order accurate schemes. The results were obtained for supersonic viscous flows over semi-infinite axisymmetric and 2-D bodies. The free stream Mach numbers were 7.78 and 16.34. The stability of Roe method with different limiters and entropy conditions were considered. The results s...

In this paper, two-dimensional and axisymmetric, time dependent transonic and supersonic flows over a projectile overtaking a moving shock wave are considered. The flow is simulated numerically by solving full time averaged Navier-Stokes equations. The equations are linearized by Newton approach.
