Flow Field Computations of Combustor-Turbine Interactions in a Gas Turbine Engine
… between the combustor and turbine. The flow field at a combustor exit shows non-uniformities in pressure, temperature, and velocity in the pitch and radial directions. This inlet profile to the turbine can have a considerable effect on the development of the secondary flows through the …

CFD Study of Taylor-Like Vortices in Swirling Flows
<p>Swirling flows are complex fluid motions that appear in various natural phenomena and man-made devices. Numerous engineering applications such as turbomachinery, jet engine combustion chambers, mixing tanks and industrial burners involve swirling flows. This wide range of applications is due to …

Non-Intrusive Sensing and Feedback Control of Serpentine Inlet Flow Distortion
… intensity found in serpentine inlet airflow was established using wall-pressure fluctuation measurements. This sensing technique was experimentally developed for aircraft with serpentine inlets in a symmetric, level flight condition. The turbulence carried by the secondary flow field …

Aerodynamics of Endwall Contouring with Discrete Holes and an Upstream Purge Slot Under Transonic Conditions with and without Blowing
… to improve aerodynamic performance by reducing secondary flow strength. The effects of endwall contouring with discrete holes and an upstream purge slot for a high turning (127") airfoil passage under transonic conditions are investigated. The total pressure loss and secondary flow field were …

Effects of Realistic Combustor Exit Profiles on a Turbine Vane Endwall
… coupled with high turbulence levels and flow field non-uniformities, make turbine vane and endwall cooling a very critical issue in engine design. To appropriately cool these surfaces, knowledge of the passage flow field and endwall temperature distribution at representative engine …

Secondary Motion in Meandering Streams: An Experimental Study
… and highly dynamic nature make the mechanics of flow in meandering streams a great interest for engineers and scientists. Meandering streams are characterized by continuous variation of curvature in the downstream direction, with subsequent loops of alternating curvature. This curvature …

ENHANCEMENT OF CONVECTIVE HEAT TRANSFER IN INTERNAL FLOWS USING AN ELECTRICALLY-INDUCED CORONA JET
… and industrial research studies. Internal flows play a major role in many applications and different methods have been utilized to augment the heat transfer to internal flows. Secondary flows consume part of the kinetic energy of the flow and disturb the boundary layer. Inducing secondary …

Numerical Simulation of Unsteady Flows of Physiological Relevance
Pulsatile flows in geometries of physiological relevance have been investigated. Atherosclerotic plaques are (initiated) near junctions and bifurcations in larger arteries. The flow in these regions is characterized by flow separation and unsteadiness, which indicates that local flow conditions …
