Fluid Flow Measurement Systems Using Hot Wire Anemometer

Abstract

The hot-wire anemometer has been used continuously since a long time as a research tool in fluid mechanics. A thorough study of this process and detailed analysis of different technique in which this method can be enhanced has been done. In hot-wire anemometry a small electrically heated element(wire) exposed to a fluid medium for the purpose of measuring a property of that fluid medium is used. Usually, the property measured is the velocity. Since these elements are sensitive to heat transfer between the element and its environment, temperature and composition changes can also be sensed.
Taking different types of probes and different types of fluid we compare the behavior of sensor so that we can determine the best condition for measurement of property particularly velocity.
