Dynamic Response of an Infinite Beam Supported by a Fluid
The objective of this study is to investigate the dynamic response of an infinite beam supported by a fluid on one side, and subjected to dynamic loading on the other side. The fluid underneath...
Computation of Wind Pressures on L-Shaped Buildings
The paper refers to the numerical simulation of turbulent wind conditions around an arbitrarily-shaped building composed of two rectangular blocks. The time-averaged Navier-Stokes equations...
Wind Effect on Oblique Motion of Two Bodies in a Uniform Flow
The wind effect on the general translational motion of a circular cylinder through an inviscid and incompressible fluid, conveyed by a uniform flow at infinity, in the vicinity of another...
Three-Dimensional Thermal Jump in Stratified Cooling Channel
This study is concerned with basic properties of three-dimensional thermal jumps. Temperature measurements obtained in three-dimensional thermal jumps are presented. The jumps analyzed...
Computation of Flow in Ice-Covered Dune-Bed Channels
A numerical method for solution of the Reynolds-averaged Navier-Stokes equations is developed to study the flow over sand dunes in two-dimensional channels. The method is applied to calculate...
Turbulence, and Energy Loss, at Combining Pipe Junctions
Efforts to measure and describe the loss of energy at 90? sharp-edged junctions are described. The work is focussed on energy losses at discharge and area ratios for which there are no...
Flow Visualization of Lid-Driven Cylindrical Cavity Flow
The lid-driven cylindrical cavity flows in the laminar region are quantitatively visualized by a new flow visualization method called the digital vector velocimetry method. Particle streak...
General Mechanism of Turbulence
By considering the vortex structures of turbulence and using the concept and theory of the pulsative convection and diffusion of instantaneous vorticity in a viscous fluid motion, the...
Wave Induced Vortex Near Seashore
The vortex motion behind submerged breakwaters in the nearshore region is studied. The RCPWAVE model (Ebersole et al., 1986) is used to calculate the wave field and thus the radiator stresses...
The Flow in the Front Stagnation Region of a Square Plate with a Small Disturbing Wire in its Upstream
The flow in the front stagnation region of a square plate was investigated experimentally in a water channel. A small wire was placed in the upstream of the square plate to create a small...
The Transverse Vortex in the Wall Regions of the Turbulent Boundary Layers in the Flows with Adverse Pressure Gradient
The vortical structures in the turbulent boundary layers in the flow with adverse pressure gradient were investigated by the hydrogen bubble technique. The vortices were visualized in...
Similarity Solutions of Starting Jets and Starting Plumes
Similarity solutions of the starting jets and the starting plumes are obtained using a one dimensional model based on the top-hat profiles and the symmetry assumption for the velocity...
Slip Velocity and Temperature Jump in Flow over Rough Surface
The expressions for the slip velocity and the temperature jump are determined and used as the boundary conditions in the calculation of turbulent flow over rough surfaces. The slip velocity...
Shear Flow Between Walls in Relative Motion
The paper reports on experiments on Couette flow, i.e., the shear-induced flow between surfaces which are in motion relative to each other. The novel aspect of the work is the appearance...
Harmonic Excitation of an Unconstrained Saturated Particle Bed
Past research on the flow of concentrated cohensinless mixtures have historically emphasized steady or quasi-steady motions while dynamic effects have received little attention in comparison....
Application of NMR to Rotating Granular Flow
Granular flow in a steadily rotating cylinder, having a large length-to-diameter ratio, is measured by nuclear Magnetic Resonance Imaging (MRI). This non-invasive technique is capable...
A Hydraulic Study of Venous Valve Closure
The functions of the veins is to convey blood from the periphery to the heart. The distribution and transportation of blood between different parts of the body is regulated by a host of...
Systolic Anterior Motion of the Mitral Valve: In Vitro Flow Studies
Using an in-vitro approach, the goal of this study was to determine and to characterize the mechanism of systolic anterior motion of the mitral valve in obstructive hypertrophic cardiomyopathy....
Leakage Characteristics of the St. Jude Heart Valve
The requirement for anticoagulant therapy in patients implanted with mechanical heart valve prostheses is well known. A plausible explanation for this requirement is that the leakage flow...
Intra Vena Cava Balloon Pumping
An innovative prototype intravenous hollow-fiber oxygenator was developed in 1984 by B.G. Hattler. The device consisted of a microporous, hollow-fiber membrane oxygenator inserted into...
