Hello,<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
I am working on implementing a new simulation to model evaporation and heat at the air-sea interface under strong winds. I have looked at tutorials and the user’s guide and have come up with some starting parameters. <\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
I was hoping I could verify that these would be sufficient before trying the model.<\/p>\n
<\/p>\n
gravity on<\/p>\n
<\/p>\n
should energy equation be checked? I don’t believe it’s necessary here<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Models:<\/p>\n
<\/p>\n
Multiphase – Eulerian – should either Multi-fluid VOF or Dens discrete phase model be applied as well?<\/p>\n
<\/p>\n
Implicit formulation<\/p>\n
<\/p>\n
Phase interaction: mass transfer – evaporation <\/p>\n
<\/p>\n
surface tension – set constant<\/p>\n
<\/p>\n
heat transfer – 2 resistance model <\/p>\n
<\/p>\n
Viscous model – k- omega SST (dispersed?)<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Species transport model – does this need to be enabled with a moist air material for effective evaporation?<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Materials:<\/p>\n
<\/p>\n
water, air, moist air? (mix of air\/water)<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Boundary conditions:<\/p>\n
<\/p>\n
no slip on most boundaries, except wind applied either at inlet or at top of domain. <\/p>\n
<\/p>\n
would consider applying periodic boundaries if I run this model with waves eventually. <\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Solution methods: These I am not so certain of <\/p>\n
<\/p>\n
Scheme: Phase coupled simple<\/p>\n
<\/p>\n
Gradient: Least squares cell based<\/p>\n
<\/p>\n
Pressure: Presto!<\/p>\n
<\/p>\n
Momentum: First order upwind<\/p>\n
<\/p>\n
Volume fraction: geo reconstruct<\/p>\n
<\/p>\n
Transient formulation: bounded second order<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
I plan to patch the water in (no waves initially).<\/p>\n
<\/p>\n
I read on another forum that the evaporation needs to be driven by the relative humidity, I want to ensure this is done properly. <\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
I would appreciate any assistance in developing this model properly!<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Thanks,
