利用立体粒子成像测速（PIV）设备对灰尘动力学温度的初级

A dusty (or complex) plasma is a four-component system composed of ions, electrons,neutral particles and charged microparticles. The presence of the microparticle (i.e.,dust) component alters the plasma environment, giving rise to a wide variety of new plasma phenomena. Recently, the Auburn Plasma Sciences Laboratory (PSL) has
acquired and installed a stereoscopic PIV (stereo-PIV) diagnostic tool for dusty plasma investigations [Thomas, et. al., Phys. Plasmas, 11, L37 (2004)]. This presentation discusses the use of the stereo-PIV technique for determining the velocity space distribution function of the microparticle component of a dc glow discharge
dusty plasma. These distribution functions are then used to make preliminary estimates of the kinetic temperature of the dust component. The data is compared to a simple energy balance model that relates the dust temperature to the electric field and
neutral pressure. 三维立体PIV Imager sCMOS PIV相机
