Fig 1. old velocity goes into CNN block, --> filter constraints, --> advected, advecting velocity components --> tensor product --> divergence --> explicit time step --> pressure projection --> new velocity
flow are considered turbulent if Re >> 1
convection: heated air rise up
advected: horizontally transfer, https://en.wikipedia.org/wiki/Advection
