Analysis of unsteady effects in shock/boundary layer interactions
The dynamics of interactions between impinging shock waves and turbulent boundary layers in supersonic flow is analyzed by mining a LES database developed for several strengths of the incoming shock. The primary effect of increasing the strength of the interaction is an increase in the size of the interaction zone and the formation of a sizeable recirculation bubble. A side consequence of the t...
متن کاملDNS of unsteady shock boundary layer interaction
A novel numerical scheme has been developed to simulate high speed viscous flows in complex geometries using unstructured grids. A characteristic–filter based shock capturing scheme is applied as a corrector step to a non–dissipative predictor scheme. This algorithm is being used to study shock turbulent boundary layer interactions and this paper presents the results of a turbulent flow at Mach...
متن کاملOscillations of the Boundary Layer and High-frequency QPOs
We observed persistent high-frequency oscillations of the boundary layer near an accreting, weakly-magnetized star in global 3D MHD simulations. The tilted dipole magnetic field is not strong enough to open a gap between the star and the disk. Instead, it forms a highly-wrapped azimuthal field near the surface of the star which slows down rotation of the disk matter, while a small tilt of the f...
متن کاملconsequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Unsteady boundary layer flow of a Casson fluid past a wedge with wall slip velocity
In this paper an analysis is presented to understand the effect of non–Newtonian rheology, velocity slip at the boundary, thermal radiation, heat absorption/generation and first order chemical reaction on unsteady MHD mixed convective heat and mass transfer of Casson fluid past a wedge in the presence of a transverse magnetic field with variable electrical conductivity. The partial differential...
