RISA Note on Film Rupture in Hydrodynamic Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical and experimental study has been made for a film repture in hydrodynamic lubrication. A model is proposed on boundary conditions at the film rupture point. It contains a pressure ...
A Survey of Heat Transfer in Separated and Reattached Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heat and mass transfer in the separated, reattached, and redeveloping regions of incompressible or compressible flow is very important in relation to many types of heat exchangers. There have ...
Turbulence Measurements in a Separated and Reattached Flow Over a Blunt Flat Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbulence measurements were made in the separated, reattached, and redeveloped regions of a two-dimensional incompressible air flow over a flat plate with finite thickness and blunt leading edge. ...
A Separated and Reattached Flow on a Blunt Flat Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Velocity, pressure, and turbulence measurements were made in the separated, reattached, and redeveloped regions of a two-dimensional incompressible flow over a flat plate with finite thickness and ...
Flow Around Two Elliptic Cylinders in Tandem Arrangement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow around two elliptic cylinders in tandem arrangement was experimentally investigated through measurements of the surface static pressure distribution and estimations of the flow parameters such ...
Linearized Potential Flow Models for Hydrofoils in Supercavitating Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A number of linearized models of fully cavitating flow about hydrofoils are investigated. Specifically, the cavity closure and wake behind the closure are examined and their effects on the ...
A Correction Formula for Wall Effects on Unsteady Forces of Two-Dimensional Bluff Bodies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In wind tunnel studies on the flow around bluff bodies accompanying a large separated wake, the walls of the test section severely effect the flow characteristics around them. Proposed in this ...
LES of Turbulent Separated Flow and Heat Transfer in a Symmetric Expansion Plane Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The LES method was applied to analyze numerically an unsteady turbulent separated and reattached flow and heat transfer in a symmetric expansion plane channel of expansion ratio 2.0. The ...
Inertia Effects on Film Rupture in Hydrodynamic Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A perturbation analysis was made to study the effect of inertia on the film rupture in hydrodynamic lubrication using a modified Reynolds equation. A simplified boundary condition at film rupture ...
Numerical Analysis on Dynamic Characteristics of Cryogenic Hydrostatic Journal Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dynamic characteristics of a two row staggered recess cryogenic hydrostatic journal bearing used in the liquid hydrogen turbopump of rocket engines for space transport systems are numerically ...
