Flow Visualization Using Plaster of Paris: NOTES

J. R. L. Allen

ABSTRACT

The pattern of motion close to the surface of a plaster of Paris model immersed in a water stream is made visible by the marks caused when bubbles of entrapped gas or pits on the surface excite a local additional turbulence which leads to differential solution of the plaster. This technique of flow visualization is illustrated by reference to motions in a constricted channel, about a cylinder mounted on a flat plate, and over a skewed negative step. This technique finds application in experimental studies of sedimentary structures.
