A Numerical Study on Mixing of Transverse Injection in Supersonic Combustor

A numerical study on mixing of hydrogen injected transversely into a supersonic air stream has been performed by solving Two-Dimensional full Navier-Stokes equations. An explicit Harten-Yee Non-MUSCL Modified-flux-type TVD scheme has been used to solve the system of equations, and a zero-equation algebraic turbulence model to calculate the eddy viscosity coefficient. The main objectives of this...

Cars Thermometry in a Supersonic Combustor for Cfd Code Validation

An experiment has been conducted to acquire data for the validation of computational fluid dynamics (CFD) codes used in the design of supersonic combustors. The primary measurement technique is coherent anti-Stokes Raman spectroscopy (CARS), although surface pressures and temperatures have also been acquired. Moderndesign-of-experiment techniques have been used to maximize the quality of the da...

Numerical Simulation to Investigate the Effect of Obstacle on Detonation Wave Propagation in a Pulse Detonation Engine Combustor

Pulse detonation technology can be a revolutionary approach for propulsion system since it offers significant fuel efficiency, higher thrust to weight ratio and low cost. Although the design concept of a pulse detonation engine is comparatively simple, but the development and stabilization of sustainable detonation wave front is difficult. Consequently pulse detonation engine technology is stil...

Development of Discontinuous Galerkin Method for Detonation and Supersonic Combustion

A discontinuous Galerkin algorithm for the simulation of realistic detonation and supersonic combustion systems is developed. This algorithm enables to consider complex and temperature/mixture-dependent thermodynamic transport properties, detailed and stiff reaction chemistry, and the robust shock-capturing. In order to evaluate all relevant algorithmic aspects, the DG-method is applied to a se...
