Advanced Temperature Compensation and Correction Techniques in Thermal Anemometry.

Thermal anemometry measurements of non isothermal flows require the use of a temperature compensation or correction method. In this article, the principles of operation of methods for reduction of temperature influence on the flow velocity measurement are discussed. The study also compares the methods and discusses the conditions for their application. The advanced temperature compensation and correction methods are presented in uniform notation and concerns hot-wire anemometers operating in the most commonly used standard constant-temperature mode.
