Onset of convection in a very compressible fluid: The transient toward steady state
Onset of convection in a very compressible fluid: The transient toward steady state
We analyze the time profile deltaT(t) of the temperature difference, measured across a very compressible supercritical 3He fluid layer in its convective state. The experiments were done along the critical isochore in a Rayleigh-Bénard cell after starting the vertical constant heat flow q. For q sufficiently well above that needed …
