Evolution of turbulence from the Rayleigh-Bénard instability


Journal Article

Measurements of heat transport through horizontal layers of fluid heated from below are reported for three aspect ratios Γ(Γ=D2d,D=diameter,d=height of the cylindrical cells). They show that for Γ=57 the fluid flow is turbulent, in the sense that it has an a nonperiodic time dependence, for numbers R>Rt with Rt≅Rc(Rc) is the critical R for onset of fluid flow). For Γ=4.72, we find Rt≅2Rc. For Γ=2.08, a quasiperiodic state exists for Rp<∼R<∼Rt, with Rp≅10Rc and Rt≅11Rc. © 1978 The American Physical Society.
