Laboratory and numerical investigations on Bénard–Marangoni convection in circular vessels
This study is concerned with supercritical Bénard–Marangoni flows of a high Prandtl number (Pr≈4000) fluid in cylinders of small to medium aspect ratio, 5⩽A⩽10. Laboratory experiments and numerical simulations, handled with an accurate spectral solver of the unsteady three-dimensional Boussinesq equ...

Zusammenfassung: | This study is concerned with supercritical Bénard–Marangoni flows of a high Prandtl number (Pr≈4000) fluid in cylinders of small to medium aspect ratio, 5⩽A⩽10. Laboratory experiments and numerical simulations, handled with an accurate spectral solver of the unsteady three-dimensional Boussinesq equations, are used to get a good understanding of the flow behavior. Experimental and numerical results are successively presented and then discussed. The confinement effects are especially pointed out and carefully analyzed. |
