LNG rollover simulation

Cees vd Ben

I am working for Fluor and looking for a party who can make simulations of rollover in an atmospheric butane storage tank for one of our clients. It is stated in numerous articles that models for this phenomenon are readily available for LNG for even these models I can not find. For the ones unfamiliar with this: it concerns the rapid mixing of two layers of liquefied butane inside an atmospheric storage tank resulting in a large amount of vapor boil-off. Thanks.
