In these cases, the rate of entropy production has been shown to be a non-monotonic function of time during the approach to steady state heat convection, which makes them different from the regime of very-slow-transfer with linearity.
In these cases, the time rate of entropy production has been shown to be a non-monotonic function of time during the approach to steady state heat convection. This makes these cases different from the near-thermodynamic-equilibrium regime of very-slow-transfer with linearity.
