Can vorticity be destroyed? Can you explain what you mean by cancel out? Is that mean that the dissipation term is 0? |

2-D Turbulence - how does it look like? After learning the basic of fluid dynamics you can look into the Annual Review of Fluid Mechanics entitled Two-Dimensional Turbulence (Vol. 44: 427-451). All the answer of your question are in it. |

Navier-Stokes system Should'n be partial derivatives? |

Navier-Stokes system That not the conventional Navier-Stokes system because it's missing the time derivative. |

If there is significant temperature difference between indoor air and outdoor air, will that significantly increase the rate of air exchange? In Rayleigh-Bénard instability the fluid at the bottom is heated, this have for effect to decrease the density of the fluid at the bottom, when the gradient become strong enough the instability take place. So yes the fluid have larger density at the top and lower density at the bottom. Using the Boussinesq approximation, the relation used between the density and the temperature is $\rho=\rho_0 \beta T$ with $\rho_0$ the characteristic density, $\beta$ the thermal coefficient (negatif) and $T$ the temperature fluctuation. |

Change in appearance of liquid drop due to gravity I'm not sure I exactly understand your question but maybe that can be interesting ems.psu.edu/~fraser/Bad/BadRain.html |

If there is significant temperature difference between indoor air and outdoor air, will that significantly increase the rate of air exchange? According to the wikipedia definition the Rayleigh-Taylor configuration is just two fluid of different density separated by an interface that occur when the lighter fluid push the denser fluid, the Rayleigh–Bénard instability configuration is denser fluid in the top of lighter fluid. I guest in some sense it's can be a RT, for me it's look like frontal instability generating gravity current. |
