Abstract

A simple inexpensive, wide field schlieren system has been developed to visualise the fluid flow patterns around heated components. The system has variable sensitivity, ranging from a high sensitivity to visualise small heat flows around the human body to a low sensitivity to visualise the large heat flows around a bunsen flume. The variable sensitivity is achieved by adjusting the distances between the optics. The wide field of view is obtained by using a novel flexible membrane mirror, providing a two foot diameter collimated light beam for inspecting the disturbed fluids.
