Liquid-Crystal-Particle Thermometry and Velocimetry System

A three-dimensional (3D) defocusing liquid-crystal-particle thermometry and velocimetry (3DDLCPTV) system has been designed and constructed (but not yet operated) for use in measuring the 3D velocity and temperature fields, respectively, in a volume of interest in a possibly turbulent flow. As its name suggests, the system utilizes defocusing digital particle-image velocimetry (DDPIV) for obtaining velocity data and liquid-crystal thermometry for obtaining temperature data.
