B21607 Flow visualization
This study
demonstrates the use of flow visualization to improve
understanding of complex flows, using hydrogen bubble and dye
injection techniques in flows involving boundary layer separation
and transition, vortex generation, and turbulence.
B21608 Deformation of continuous media
Here's an
introduction to the concepts of rotation, strain, principal axes,
and deformation rate by analysis of patterns marked on the surface
of glycerine moving in a rectilinear Couette flow.
B21609 Pressure fields and fluid acceleration.
This program
presents experiments in a small water tunnel, demonstrating the
connection between velocity and pressure fields, primarily in
diffusers, ventures, and channel bends.
B21610 Surface tension in fluid mechanics.
Here are experiments
illustrating effects of surface tension, including soap film
intersections, break-up of jets and sheets into droplets, and slow
motion splashing of a droplet.
B21611 Waves in fluids
This feature
presents experimental demonstrations of concepts in one
dimensional wave motion using a water channel, a flume, and shock
tubes.
B21612 Secondary flow.
This program
provides demonstrations of secondary flows in a sink vortex tank
and a bend in an open channel.
B21613 Rheological behavior of fluids.
Non-Newtonian
viscous fluid behavior is illustrated using several different
substances, and is contrasted to Newtonian viscous fluid behavior.
B21614 Boundary layer control.
This program shows
the effects of geometric shaping, suction, and blowing on airfoils
in controlling boundary layers transition and separation to
produce higher lift and/or lower drag.
B21615 Magneto-hydrodynamics.
Experiments using
transparent electrolyte, mercury, and liquid sodium potassium
alloy demonstrate the interactions between electromagnetic and
velocity fields.
B21617 Low-Reynolds number flow.
This fascinating
program demonstrates the phenomenon of "inertiafree" flows in
which viscous forces dominate the balance of forces.
B21618 Stratified flow.
Experiments in this
program 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.
B21620 Cavitation.
Cavitation is seen
on hydrofoils, marine propellers, pumps, turbines and dam
spillways. Flow speed, hydrofil incidence, ambient pressure, and
propellers RPM are varied to demostrate their effects on the
strength and extent of
the
cavitation region.
B21621 Eulerian and Lagrangian descriptions in fluid
mechanics.
This program shows
two principal ways of describing fluid motion, using
computer-generated displays of displacement, velocity, and
acceleration fields for several simple flows.
B21622 Rarefied gas dynamics.
This program
illustrates the evolution of flow fields as density is varied from
continuum levels to the rarefied levels of free-molecule flow.
B21623 Fundamentals of boundary
layers.
This program
demonstrates the basic aspects of viscous incompressible boundary
layers: what causes them, how they grow, and the differences in
behavior of laminar and turbulent layers.
B21624 Rotating flows.
Phenomena associated
with rotation of homogeneous fluids are illustrated.
B21625 Aerodynamic generation of
sound.
This program
describes the mechanism of sound generation by turbulence
resulting from instability of steady flow. Elementary source
models are illustrated.
B21626 Turbulence.
This program
illustrates many of the important aspects of turbulence: effect of
Reynolds number on inception, increased pressure drop in pipe
flow, turbulent transport of momentum and scalar properties, and
others.
