Phenomena associated with the rotation of homogeneous fluids. Includes horizontal trajectories in surface gravity waves, low and high Rossby number flows around spheres, Taylor walls, normal modes of inertia...
The experiments show that density variations, together with gravity, make possible forces that can generate internal waves; inhibit turbulent diffusion, or create strong velocity gradients and jets....
Describes the mechanism of sound generation by turbulence resulting from an instability of steady flow. Elementary source models are illustrated and their fields visualised on a ripple tank. Quadrupoles are...
Cavitation is seen on hydrofoils, marine propellers, pumps, turbines, and dam spillways. Shows some of the harmful or annoying effects of cavitation, such as noise, increased lift and damage to solid...
Illustrates the two principal ways of describing fluid motion, using computer-generated displays of displacement, velocity and acceleration fields for single flows. The physical relationship between the two...
The main experiment, generation of surface waves by wind in a water channel, is used to illustrate the general features of flow instability. The curve of neutral stability is developed by systematically...
Demonstrates basic aspects of viscous incompressible boundary layers: 1) what causes them; 2) how they grow; 3) how they respond to pressure gradients; 4) the main stages in the transaction of laminar layers...
Demonstrates phenomena of ‘inertia-free’ flows in which viscous forces dominate in the balance of forces. Topics include: relative importance of inertial and viscous forces as Reynolds number is varied,...
Shows the following aspects of turbulence: effect of Reynolds number on inception, increased pressure drop in pipe-flow, efficient mixing, turbulent transport of momentum and scaler properties, Reynolds...
Shows gas flow at various pressures and speeds using initially a sodium molecular beam and then actual gas flow in a supersonic flow chamber. Bow and barrel shock waves are shown together with scattering...
