Flux Limited Dissipation Schemes for High Speed Unsteady Flows

Within the framework of the Local Extremum Diminishing (LED) or Essentially Local Extremum Diminishing (ELED) principle, efficient approaches to obtain a class of non-oscillatory high resolution schemes are presented. The LED principle requires that local maxima should not increase and local minima should not decrease to produce a monotonicity preserving scheme for scalar hyperbolic conservatio...

A Solution Adaptive Grid Method for Calculation of High Speed Flows around Blunt Body Configurations

Extension of a solution adaptive grid method to hypersonic flows is presented. Fully unstructured triangular grids are generated in an automatic manner and further refined by adapting to the flow features. Two-dimensional inviscid flow is simulated by numerical solution of Euler equations. A cell-centered finitevolume scheme is used and the steady state solution is obtained using an explicit mu...

Application of Pressure-Sensitive Paints to Unsteady and High-Speed Flows

The Pressure-Sensitive Paint (PSP) technique allows the global pressure mapping of surfaces under aerodynamic conditions. The present study involves the application of TrisBathophenanthroline Ruthenium Perchlorate based PSP, developed in-house, to two different cases; a) the flow through a sonic nozzle, and b) the examination of the effect of dimples on glancing shock wave turbulent boundary la...
