Abstract
A non-invasive method to simultaneously measure the three-dimensional velocity and temperature fields in thermal convection would be a very valuable tool for studying the underlying thermal transport processes, which are important in nature and in many technical applications. With our study we aim at bridging this gap in the long run by combining Tomographic Particle Image Velocimetry (Tomo-PIV) with liquid crystal thermometry. As a first step towards this goal, we applied Tomo-PIV to Rayleigh-Bénard convection (RBC) of water in a cubic sample to obtain the instantaneous three-dimensional velocity field at Ra= 1.0 · 10^10 and Pr= 6.9. A comparison of the measured large-scale circulation with results from direct numerical simulations (DNS) and planar PIV measurements demonstrates the reliability of the Tomo-PIV technique. This is a prerequisite for employing Thermochromic Liquid Crystals (TLC) as tracer particles.
