Lagrangian temperature, velocity and local heat flux measurement in Rayleigh-Benard convection [PDF]

open access: yes, 2007
We have developed a small, neutrally buoyant, wireless temperature sensor. Using a camera for optical tracking, we obtain simultaneous measurements of position and temperature of the sensor as it is carried along by the flow in Rayleigh-B\'enard ...
