Time dependence in rayleigh-Bénard convection with a variable cylindrical geometry

Published

Journal Article

Studies of the first time dependence in Rayleigh-Bénard convection in He4 are reported. The aspect ratio Γ could be varied continuously. Data at 31 Γ values with 4<Γ<13 show that near onset the first time dependence is always periodic and associated with changes in the heat transport. The dominant periodicity has a nonzero amplitude, A, and vanishing frequency at onset. Changes in A with Γ show wave-number effects. Except for the time dependence, the transition is consistent with predictions for the skew-varicose instability. © 1983 The American Physical Society.
