Two-Phase Flow From a Stratified Region Through a Small Side Branch
(The American Society of Mechanical Engineers (ASME), 1998)Experimental data are presented for the mass flow rate and quality of two-phase (air-water) discharge through a small branch (6.35 mm i.d.) located on the side of a large reservoir under ... -
Axial Pressure Distribution in the Entrance Region of Packed Beds of Spheres
(The American Society of Mechanical Engineers (ASME), 1998) -
Nonlinear Rupture Theory of a Thin Liquid Film With Insoluble Surfactant
(The American Society of Mechanical Engineers (ASME), 1998)Effects of insoluble surfactant on the dynamic rupture of a thin liquid film coated on a flat plate are studied. The strong nonlinear evolution equations derived by the integral method are ... -
Analytical Solution to Flux Enhancement in Laminar Concentrically Stratified Pipe Flow of Bingham and Newtonian Fluids
(The American Society of Mechanical Engineers (ASME), 1998) -
Transport of Heavy Particles in a Three-Dimensional Mixing Layer
(The American Society of Mechanical Engineers (ASME), 1998)Particle transport in a three-dimensional, temporally evolving mixing layer has been calculated using large eddy simulation of the incompressible Navier-Stokes equations. The initial fluid velocity ... -
On the Choking of the Flow of Piezoviscous Liquids
(The American Society of Mechanical Engineers (ASME), 1998)Experimental evidence for choking of a piezoviscous fluid in a capillary tube is presented. It is shown that under a nearly isothermal condition, it is possible for the flow to experience ... -
A Survey of Time-Averaged Characteristics of Laminar and Turbulent Horseshoe Vortices
(The American Society of Mechanical Engineers (ASME), 1998)The time-averaged kinematical and dynamical characteristics of the junction vortex system in front of a symmetrical obstacle are systematically analyzed for both laminar and turbulent flows. A ... -
Studies on the Behavior of Droplets and the Air Flow in a Hollow-Cone Spray
(The American Society of Mechanical Engineers (ASME), 1998)Experimental and numerical investigations are made on the behavior of droplets in a hollow-cone spray paying attention to the liquid sheet formed at the orifice of pressure-swirl atomizer. ... -
The TAR Model for Calculation of Droplet/Wall Impingement
(The American Society of Mechanical Engineers (ASME), 1998)In this paper, we present a new model, called the TAR model, for calculation of droplet/wall impingement. Using this model, we find that the critical Weber number for rebound is not a constant. ... -

Effects of Wall Shape on Flow Regimes and Performance in Straight, Two-Dimensional Diffusers
(The American Society of Mechanical Engineers (ASME), 1967)Three diffuser sets (N/W1 , held constant in each set) were built and tested for performance and flow regime over a range of total area ratios, AR, which yielded unstalled and stalled flows. ... -
Boundary-Layer Control by Electric Fields
(The American Society of Mechanical Engineers (ASME), 1998) -
A Numerical Methodology to Predict Exhaust Plumes of Propulsion Nozzles
(The American Society of Mechanical Engineers (ASME), 1998)A simple methodology to simulate the mixing layers that occur between nozzle exhaust jet and the external air is proposed. The method is based on a simplified model of the plume, that replaces ... -
Unbalanced Hydraulic Forces Caused by Geometrical Manufacturing Deviations of Centrifugal Impellers
(The American Society of Mechanical Engineers (ASME), 1998)When an impeller has geometrical manufacturing deviations, synchronous vibration occurs from an unbalanced hydraulic force rotating with the impeller. This phenomenon is termed “Hydraulic unbalance.” ... -
Drop Size and Velocity Measurements in an Electrostatically Produced Hydrocarbon Spray
(The American Society of Mechanical Engineers (ASME), 1998)Liquid hydrocarbons are difficult to atomize electrostatically at practical flow rates due to their high resistivities and low concentration of charge carriers. However special “charge injection” ... -
Turbulent Flow Past an Array of Bluff Bodies Aligned Along the Channel Axis
(The American Society of Mechanical Engineers (ASME), 1998)Computations and measurements of time mean velocities, total fluctuation intensities, and Reynolds stresses are presented for spatially periodic flows past an array of bluff bodies aligned along ... -
Three-Dimensional Blade Boundary Layer and Endwall Flow Development in the Nozzle Passage of a Single Stage Turbine
(The American Society of Mechanical Engineers (ASME), 1998)The three-dimensional viscous flow field development in the nozzle passage of an axial flow turbine stage was measured using a “x” hot-wire probe. The measurements were carried out at two axial ... -
A Design Method for High-Speed Propulsor Blades
(The American Society of Mechanical Engineers (ASME), 1998)This study uses a nonlinear optimization method coupled with a vortex lattice cavitating propeller analysis method to design efficient propeller blades. Different constraints are imposed to improve ... -
Steady and Unsteady Flow Field at Pump and Turbine Exits of a Torque Converter
