Due to their common occurrence and fundamental role in human-realized processes natural phenomena, turbulent flows are subject constant research. One of the research tools used these studies hot-wire anemometers. These instruments allow for measurements a wide range both velocities frequencies fluctuations. This article describes new indirect method determining bandwidth shape constant-temperat...

• Hot wire anemometers are sensitive to absolute values of air and sensor temperatures. Air properties should be evaluated at the mean Actual for need not determined, only temperature derivatives. Influence from expressed as functions Variations in fluid most important error source hot-wire anemometer measurements must sometimes compensated for. Although many compensation schemes have been prop...

Abstract The wake past a smooth cylinder perpendicular to the flow is studied 15 D (cylinder diameters) downstream by using particle image velocimetry (PIV). Spatial shedding period used estimate spatial Strouhal number (Sh) and compare with time-resolved hot-wire anemometer (HWA). vortices are detected within fluctuation field. statistical vortex properties do not change explored range of Reyn...

A wind tunnel investigation was performed to study the flow field over a 70° swept sharped edge delta wing model at high angles of attack. The experiments were conducted in the subsonic wind tunnel at the Department of Mechanical Engineering, Sharif University of Technology. Velocity profiles have been measured using a special pitot tube and hot wire anemometer at angles of attacks of 10 to 35 ...

the aerodynamics of road vehicles has frequently been studied in simplified geometries to separate the effect of various components on aerodynamic drag and on near wake flow dynamics. in this work, the characteristics of the near wake of a notch-back car model were investigated, using hot-wire anemometer. the main objectives of this study are to gain a better understanding of the flow structure...

In this study, convective heat transfer phenomena were investigated by means of a Guarded Hot Box (GHB) apparatus. An experimental setup characterized air and surface temperature probes, hot-wire anemometer was used. Five small fans installed in the metering chamber to generate forced flow different velocity values. So, GHB used for investigating influence speed values on internal coefficients....
