Tobit Caudwell (LEGI): Heated wall and establishment of stratification in an enclosure

Wall convection produced by hot walls is of great interest to many
industrial and environmental applications.
In this experimental-theoretical investigation we consider a turbulent
plume generated by an isothermal wall in an enclosure, and the formation
of the heat stratification in the interior. The evolution of the plume
near the wall and the temperature stratification are measured across a
plane, using simultaneous LIF and PIV measurements that allows to give a
precise description of the dynamics of the system. Our detailed results
allow us to make detailed comparisons between experiments and several
models derived from entrainment plume theory, in the stratified region as
well as in the plume itself. Improvements are proposed to increase the
accuracy of the theory.
