To develope a reliable method for modelling fire case scenarios within the road tunnels and observing the effects of the skewed velocity, experimental and numerical approach is used. Experimental results obtained from a laboratory tunnel-model instal

A very high resolution minimal channel flow DNS was used to examine, virtually, the ability of various multi-sensor hot-wire probe configurations to measure the statistics of velocity gradient components. Various array and sensor configurations and t

A highly resolved turbulent channel flow direct numerical simulation (DNS) with Re τ = 200 has been used to investigate the influence of the velocity gradients on the measurement accuracy of a hot-wire probe capable of measuring all three velocity c

This article reviews the principal experimental methods currently available to simultaneously measure all the terms of the velocity gradient tensor of turbulent flows. These methods have been available only for a little more than 20 years. They have

The use of hot-wire anemometry in carbon dioxide flow under supercritical conditions has been analyzed and implemented for the first time. A two-sensor probe to simultaneously measure streamwise velocity and temperature in this flow has been designed

The uniqueness range of hot-wire probes to simultaneously measure all three velocity components is analysed analytically. Expressions defining the uniqueness cone half-angle are presented for triple as well as for quadruple sensor configurations. Usi

A method to calibrate hot-wire X-array probes in the low-speed (under 3 m s−1) range, has been proposed and analysed. It is based on a second-order polynomial fit describing the yaw dependence of the probe sensor response. The method has been exten

The measurement accuracy of different hot-wire probes possessing between two and 12 sensors is analyzed. Experimental data were sampled in a round free jet and in a zero-pressure-gradient turbulent boundary layer by a 12-sensor hot-wire probe. Testin

A probe made up of one cold and two hot-wire sensors, to simultaneously measure the temperature and velocity fluctuations, has been designed and analysed. In order to optimize the probe's geometrical configuration and reduce mutual interference of th

A highly resolved turbulent channel flow direct numerical simulation (DNS) with Res = 200 has been used to investigate the influence of the arrangements of the arrays (array configurations), within the sensing area of a multi- array hot-wire probe on
