Particle image velocimetry for natural convection in a cube at high Rayleigh numbers
… the dominant flow structures. The low turbulence Rayleigh number regime 5.08E7<Ra<3.40E8 is examined for the first time and experimental results including streamlines, the two velocity components in the vertical and horizontal direction, Reynolds stresses, swirling strength and vorticity are …

A New Numerical Method--Asymptotically Simplified Iteration Method With Patching as Applied to Free and Mixed Convection Heat Transfer
… (ASIMP). It is based on the natural structure of high Rayleigh number free convection, which consists of thin thermal and viscous boundary layers surrounded by a region of negligible viscous and conductive influences. Iteration techniques appropriate for each region are obtained from …

Filling flows induced by a convector in a room
… in water with a saline solution to ensure high Rayleigh numbers. Diagnostic techniques involve a combination of a shadowgraph method, a dye-attenuation method, direct salinity measurements and a new application of Particle Image Velocimetry (PIV). Interesting insight into convector-induced …
