I'm hoping to model the impact different levels of insulation would have on heat loss from an in-ground pool.

I'm thinking this is basically just a basement with water instead of air and plan to model it as such.

I'm wondering if there is a way to account for the difference between air and water when modelling convective heat transfer as i assume this will be the major issue with this model.

Also curious to hear folks' general thoughts on how best to model heat transfer from an in-ground pool.

Thanks in advance.
