Testing of Transition-Region Models
(The American Society of Mechanical Engineers (ASME), 1992)An approach for the comprehensive testing of transition-region models is described. This approach emphasizes the need to evaluate the models in all of the flow scenarios for which they are ... -
Airblast Atomization of Viscous Newtonian Liquids Using Twin-Fluid Jet Atomizers of Various Designs
(The American Society of Mechanical Engineers (ASME), 1992)Airblast atomization of viscous Newtonian liquids is carried out using coaxial twin-fluid jet atomizers of different nozzle sizes, slit angles, and slit cross sections for air flow. As the ... -
Pressure Drop in Single-Phase and Two-Phase Couette-Poiseuille Flow
(The American Society of Mechanical Engineers (ASME), 1992)This paper is concerned with axial pressure gradient in single-phase and two-phase flow at low void fraction in a narrow annular space between two concentric cylinders, the inner one rotating. ... -

Studies on Cavitation Inception Process in Separated Flows
(The American Society of Mechanical Engineers (ASME), 1992)Studies related to cavitation inception process in separated flows are reported. Experimental observations of bubble appearance in grooves with laminar or turbulent boundary layer over them have ... -
Dynamics of Attached Cavities on Bodies of Revolution
(The American Society of Mechanical Engineers (ASME), 1992)Attached cavitation was generated on two axisymmetric bodies, a Schiebe body and a modified ellipsoidal body (the I. T. T. C. body), both with a 50.8 mm diameter. Tests were conducted for a ... -
The Effect of Friction on Flow Distribution in Dividing and Combining Flow Manifolds
(The American Society of Mechanical Engineers (ASME), 1992)An analytical solution was obtained to evaluate the effect of friction on flow distribution in both dividing and combining flow manifolds. The governing equation follows the derivation given by ... -
Numerical Simulation of Heavy Particle Dispersion Time Step and Nonlinear Drag Considerations
(The American Society of Mechanical Engineers (ASME), 1992)Numerical experiments can be used to study heavy particle dispersion by tracking particles through a numerically generated instantaneous turbulent flow field. In this manner, data can be generated ... -
Flow Development and Analysis of MHD Generators and Seawater Thrusters
(The American Society of Mechanical Engineers (ASME), 1992)The flow characteristics inside magnetohydrodynamic (MHD) plasma generators and seawater thrusters are analyzed and are compared using a three-dimensional computer model that solves the governing ... -
Thin Flowing Liquid Film Thickness Measurement by Laser Induced Fluorescence
(The American Society of Mechanical Engineers (ASME), 1992)An optical technique is described for determining, in a physically nondisturbing manner, the thickness of a thin flowing liquid film. The technique is based on measurement of the fluorescent ... -
Turbulence Modeling and Simulation of Atmospheric Boundary Layers
(The American Society of Mechanical Engineers (ASME), 1992)The essence and shortcoming of turbulence modeling and simulation of atmospheric boundary/surface layers are discussed. The present approach rests on the extensively tested and widely used ... -
