Principle of a CT hot-wire anemometer. A hot-wire anemometer, working in the CT mode, is capable of measuring rapid velocity fluctuations. This is an advantage in the measurement of flow turbulence and is also the main area of application for the hot-wire anemometer. It is an instrument ...
The working principle of constant temperature anemometer (CTA), used for fluid velocity and/or turbulence measurements, is based on convective heat transfer from a sensor (a hot wire or a hot film) to the fluid being measured. Response of a CTA, working in temperatures other than its ...

In the present work, a method for calibrating hot-wire anemometers for low-speed measurements is described. After a brief recall of the working principle of the instrument, the problems connected with the measurement of low-speed flows are described. A method for overcoming these problems is ...

The majority of these sensors are based on different methods of thermal anemometry because this is quite a simple yet reliable principle [2]. Our sensor consists of a single tiny wire integrated into a polymer-based microfluidic platform; therefore, a simple integration in many different devices ...
The constant temperature anemometer was used to study the turbulent structure behind the airfoil. The basic principle of this device is to compensate for the thermal state of the hot wire [39,40]. The Wheatstone Bridge is used to measure the variation of the wire resistance relative to its te...
