多重介电阻挡放电,DBD,离子体制动器中流场,速度场,速度矢量场检测方案(粒子图像测速)
This work presents preliminary results of flow separation control from the flap of a high-lift airfoil using a single dielectric barrier discharge (DBD) plasma actuator. Control effectiveness is investigated for two actuator locations as well as various reduced frequencies, applied voltages and waveforms. Results show that a single DBD plasma actuator located at the flap shoulder can slightly increase or reduce the size of the time-averaged separation bubble over the flap depending on the frequency of actuation. This effectiveness is not improved by an increase in applied voltage or a change from a sinusoidal to positive sawtooth waveform for the cases examined. Spatial eigenmodes calculated from twocomponent PIV using POD show that a single DBD plasma actuator at the flap shoulder can have a significant effect on the structure of higher order modes. However the corresponding energy of these modes is low in comparison to the dominant modes in the wake. Nomenclature Cp =

圆柱尾迹,湍流,三维相干结构中3D3C速度矢量场,速度场,体视速度场,层析速度场检测方案(粒子图像测速)
The wake of a circular cylinder at Re = 2700 is investigated by means of Tomographic PIV (Tomo-PIV), a recently developed three-dimensional velocimetry technique. The paper presents the principles of Tomo-PIV and discusses in details the implementation of the technique to the experimental conditions. With a measurement volume of approximately 40x40x10 mm2 two configurations are chosen in order to describe both the 2D wake features and the span wise organization of secondary rollers dominating the 3D flow organization. The present data allow to directly evaluate the measurement error imposing mass conservation inside the volume (viz. solenoidal velocity field). The visualization of the wake instantaneous structure is obtained by means of vorticity vector magnitude iso-surfaces, or decomposing the vorticity in the span wise and stream-wise(normal)/bi-normal component, which return the separate contribution of the Kármán rollers and the interconnecting structures between them respectively. The properties of the secondary rollers are given in terms of span wise wavelength, peak vorticity, vorticity stretching and their size and shape. A value of the span wise wavelength λ z/D = 1.2 is recurring and the rollers organization into pairs is found to be similar to the instability Mode B occurring in lower Reynolds number wakes investigated with previous studies.

气体,液体,流体中PLIF,激光诱导荧光,浓度场,混合度,速出场检测方案(流量计)
For the enhancement of many technical processes like reacting flows, mixing in chemical reactors or mixture formation in combustion engines the knowledge of spatial distribution of species is of great importance. The planar laser-induced fluorescence (PLIF) technique is a well established method to get 2-dimensional maps of concentration or mixture-ratio in a specific plane in the volume of interest. In our recent work we were able to validate a PLIF technique for the quantitative detection of fuel/air ratios (FARLIF) which will be used for mixture-formation investigations in optical engines [1, 2]. In many applications – like mixture-formation in combustion engines – not only the actual species or mixture distribution is of interest. The temporal evolution, the dynamics of the species distribution is often a key for the understanding and improvement of the fluid-dynamic processes.

溪红点鲑、背鳍、臀鳍中水动力学功能,流场,速度场,速度矢量场检测方案(粒子图像测速)
Recent kinematic and hydrodynamic studies on fish median fins have shown that dorsal fins actively produce jets with large lateral forces. Because of the location of dorsal fins above the fish’s rolling axis, these lateral forces, if unchecked, would cause fish to roll. In this paper we examine the hydrodynamics of trout anal fin function and hypothesize that anal fins, located below the fish’s rolling axis, produce similar jets to the dorsal fin and help balance rolling torques during swimming. We simultaneously quantify the wake generated by dorsal and anal fins in brook trout by swimming fish in two horizontal light sheets filmed by two synchronized high speed cameras during steady swimming and manoeuvring. Six major conclusions emerge from these experiments.
