Simultaneous temperature and velocity Lagrangian measurements in turbulent thermal convection
O. Liot, F. Seychelles, F. Zonta +6
We report joint Lagrangian velocity and temperature measurements in turbulent thermal convection. Measurements are performed using an improved version (extended autonomy) of the ne…
Characterizing flows with an instrumented particle measuring Lagrangian accelerations
Robert Zimmermann, Lionel Fiabane, Yoann Gasteuil +2
We present in this article a novel Lagrangian measurement technique: an instrumented particle which continuously transmits the force/acceleration acting on it as it is advected in…
Measuring Lagrangian accelerations using an instrumented particle
Robert Zimmermann, Lionel Fiabane, Yoann Gasteuil +2
Accessing and characterizing a flow impose a number of constraints on the employed measurement techniques; in particular optical methods require transparent fluids and windows in t…
Rotational intermittency and turbulence induced lift experienced by large particles in a turbulent flow
Robert Zimmermann, Yoann Gasteuil, Mickael Bourgoin +3
The motion of a large, neutrally buoyant, particle, freely advected by a turbulent flow is determined experimentally. We demonstrate that both the translational and angular acceler…
Tracking the dynamics of translation and absolute orientation of a sphere in a turbulent flow
Robert Zimmermann, Yoann Gasteuil, Mickael Bourgoin +3
We study the 6-dimensional dynamics -- position and orientation -- of a large sphere advected by a turbulent flow. The movement of the sphere is recorded with 2 high-speed cameras.…
Lagrangian temperature, velocity and local heat flux measurement in Rayleigh-Benard convection
Yoann Gasteuil, Woodrow Shew, Mathieu Gibert +3
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 t…
An instrumented tracer for Lagrangian measurements in Rayleigh-Bénard convection
Woodrow L. Shew, Yoann Gasteuil, Mathieu Gibert +2
We have developed novel instrumentation for making Lagrangian measurements of temperature in diverse fluid flows. A small neutrally buoyant capsule is equipped with on-board electr…
