Volumetric 3-component velocimetry measurements of the flow field on the rear window of a generic car model

Abstract

Volumetric 3-component Velocimetry measurements are carried out in the flow field around the rear window of a generic car model, the so-called Ahmed body. This particular flow field is known to be highly unsteady, three dimensional and characterized by strong vortices. The volumetric velocity measurements from the present experiments provide the most comprehensive data for this flow field to date. The present study focuses on the wake flow modifications which result from using a simple flow control device, such as the one recently employed by Fourrié et al. [1]. The mean data clearly show the structure of this complex flow and confirm the drag reduction mechanism suggested by Fourrié et al. The results show that strengthening the separated flow leads to weakening the longitudinal vortices and vice versa. The present paper shows that the Volumetric 3-component Velocimetry technique is a powerful tool used for a better understanding of a threedimensional unsteady complex flow such that developing around a bluffbody

Investigation of the simultaneous volumetric 3-component flow field inside a hydrocyclone

“…However, the development of imaging measurement methods has led to the formulation of threedimensional threecomponent (3D3C) measurement techniques to solve the aforementioned limitations. Volumetric 3-component velocimetry (V3V) visualizes the entire field for flow field measurement [23][24][25]. The comparison of V3V with PIV and LDV/PDPA is shown in Table 2.…”

Investigation of transient cooling of an automobile cabin with a virtual manikin under solar radiation

“…With this respect, engineers have to consider energy consumption during heating or cooling of an automobile cabin due to legal restrictions and efficient use of energy resources. The experimental studies have been also performed under different environmental conditions [18][19][20]. Thus, engineers have to design more effective HVAC systems of automobiles under different environmental conditions.…”

Estimation of laser-Doppler anemometry measuring volume displacement in cylindrical pipe flow

“…Laser-Doppler anemometry (LDA) is an optical technique for measurement of velocity and turbulence in gas, liquid, multiphase fluids, chemically reacting flows, in combustion, flame, wave tanks, rotating machinery, wind or water tunnels, micro and macro channels, in biomedical applications, atmospheres, oceanography and in other scientific, and industrial research, where the conventional techniques can not be performed successfully [1][2][3][4][5][6][7][8][9][10][11]. This optical method of local instantaneous velocity measurement is non-contact, non-intrusive and can be employed where the physical sensors are difficult or impossible to use.…”
