Rayleigh-Bnard Rotating convection for high Rayleigh numbers
Christie K. Chew D.P. Lathrop & G. Bewley University of Maryland, College Park Institute for Research in Electronics and Applied Physics
What is convection?
Warm water molecules are less dense than cooler ones, buoyancy causes the warmer molecules to rise and cooler ones to fall Rayleigh-Bnard convection Rayleigh Ra number classifies the convection: Ra = gL3T Other number classifiers:Rossby Ro = u/L, Reynolds number Re = uL/
