The calibration procedure for a hot-wire anemometer system operating in a non-isothermal pressure-variant flow field is presented. Sensing of atmospheric velocity and temperature fluctuations from an altitude-variant platform using hot- wire anemometry equipment operating in both constant- temperature and...
Problems associated with collecting hot-wire anemometry data in a non-laboratory environment are discussed. Example data sets of temperature and velocity collected during the kite/tethered-balloon experiments are presented. !21Ronald J. HugoAir Force Research Lab....

Hot-film (or hot-wire) anemometry is based on the phenomenon that the heat transfer from an electrically heated film or wire is a function of the fluid motion past the sensor. It is extensively used in study of turbulence, where it is assumed that there is an exponential relation between ...
Hot-wire anemometryTurbulenceTurbomachineryA technique based on a rotated hot wire has been developed to characterise the unsteady, three-dimensional flow field between compressor blade rows. Data are acquired from a slanted hot wire rotated through a number of orientations at each measurement point....
Experimental investigation on the dynamic characteristics of vortex flow in a cyclone was performed, particularly focused on the effects of the gas leakage from the dipleg. The instantaneous tangential velocities were measured by hot wire/film anemometry (HWFA) under the conditions of different gas ...
microfluidic flowmeter; flow sensor; hot Wollaston wire; polymer-based sensor1. Introduction Flow sensors in microfluidic devices are needed to precisely control fluid flow and handle tiny fluid volumes [1]. The majority of these sensors are based on different methods of thermal anemometry because ...
