RISNumerical Modeling of Freestream Turbulence Decay Using Different Commercial Computational Fluid Dynamics Codes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work models the spatial decay of freestream turbulence using three different commercial computational fluid dynamics (CFD) codes: Fluent, star-ccm+, and cfx. The two-equation shear stress transport k–ω (SST-k–ω) steady ...
Experimental and Numerical Study of Flow Structures Associated With Low Aspect Ratio Elliptical Cavities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow regimes associated with 2:1 aspect ratio elliptical planform cavities of varying depth immersed in a turbulent boundary layer at a Reynolds number of 8.7 أ— 104, based on the minor axis of the cavity, have ...
Wall Shear Stress Determination in a Small-Scale Parallel Plate Flow Chamber Using Laser Doppler Velocimetry Under Laminar, Pulsatile and Low-Reynolds Number Turbulent Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The parallel plate flow chamber (PPFC) has gained popularity due to its applications in fields such as biological tissue engineering. However, most of the studies using PPFC refer to theoretical relations for estimating ...
Quantification of Morphological Modulation, F-Actin Remodeling, and PECAM-1 (CD-31) Redistribution in Endothelial Cells in Response to Fluid-Induced Shear Stress Under Various Flow Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cardiovascular diseases (CVDs) are the number one cause of death globally. Arterial endothelial cell (EC) dysfunction plays a key role in many of these CVDs, such as atherosclerosis. Blood flow-induced wall shear stress ...
Investigation of the Performance of Turbulence Models With Respect to High Flow Curvature in Centrifugal Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The goal of this research is to evaluate the performance of three turbulence models with respect to flow with high curvature in a centrifugal compressor stage designed for an aeroengine. The effectiveness of the curvature ...
The Effect of the Nozzle Top Lip Thickness on a Two-Dimensional Wall Jet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of the nozzle top lip thickness on a two-dimensional wall jet was examined experimentally in a wind tunnel using hot-wire anemometry. Lip thicknesses of 0.125b, 0.5b, 1b, and 2b, where b is the jet nozzle height, ...
