Wall Pressure and Effective Wall Shear Stresses in Heat Exchanger Tube Inlets With Application to Erosion-Corrosion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Inclined flow into tube inlets is studied in order to identify flow characteristics associated with enhanced erosion-corrosion rates at tube inlets. Measured wall pressures and shear stresses are ...
Velocity Field and Entrainment of a Pulsed Core Jet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A pulsed core jet is one consisting of a steady annular flow with a core, the mass flow of which is unsteady. The combined jet exhausts into a still environment. The velocity field and ...
Application of the k–ε Turbulence Model to the Simulation of a Fully Pulsed Free Air Jet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The work describes application of the k–ε turbulence model to a fully pulsed air jet. The standard model failed to predict the change in slope of the velocity decay where the jet changes ...
A Modified Form of the k-ε Model for Predicting Wall Turbulence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The high Reynolds number form of the k-ε model is extended and tested by application to fully developed pipe flow. It is established that the model is valid throughout the fully turbulent, ...
Velocity Bias Associated With Laser Doppler Anemometer Controlled Processors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The controlled processor has been proposed as a means of avoiding velocity bias in laser Doppler anemometry. A theoretical model is presented to show that results free of bias can be obtained ...
