In this paper, we want to find a corner enhancement curve deformation approach. We consider General Geometric Heat Flow(GGHF) as a general deformation approach, and the evolution of curvature in the approach is derived. The criteria of curvature scale space are proposed and subjected to the GGHF. The conditions under which the corner can be enhanced are also studied. From all these constraints,...

The interaction between corner flow and heat transfer is very common in the internal external of hypersonic vehicle surface, but it not clear how wall thermal boundary condition affects supersonic layer. In present study, Reynolds stress model used to solve Reynolds-averaged Navier–Stokes equations. results show that when symmetrical temperature Tw less than or equal recovery Taw, mean velocity...

conclusion in cases with critical atherosclerotic disease of anterior tibial artery, pta-based biphasic or triphasic retrograde collateral flow prevents ischemia, whereas monophasic support or no retrograde flow remains incapable. results in the patient group, 31 lower limb arteries, of total of 17 cases, were included. after compression maneuver, dpa in 11 cases (six right, five left) showed r...

Deflected control surfaces can be used as variable camber in different flight conditions, and a convex corner resembles simplified configuration for the upper surface. This experimental study determines presence of passive vortex generators, VGs (counter-rotating vane type), on shock-induced boundary layer separation transonic convex-corner flow. The mean surface pressure distributions h/? = 0....

Dual turbocharger turbine is fed by an unequal out-of-phase mass flow charge almost all the time which have significant effects on its performance parameters and flow phenomena which are not well known. Besides fully understanding the flow behavior in the radial turbine suffers from lack of detailed information about the secondary flows. This article studies the secondary flow structure within ...
