(32d) Multiscale Process Simulation By Combining CFD and Subgrid Modeling
In this contribution we show a new automated coupling method between the CFD-tool STAR-CCM+ by Siemens PLM and gPROMS by PSE, where STAR-CCM+ solves for all flow properties and gPROMS evaluates the fine scales based on the solution provided by STAR-CCM+. The coupling between both codes is done in an automatic way. This includes the domain decomposition, the calculation of and the transfer of all relevant variables.
The details of the coupling as well as the advantage of this approach is demonstrated based on a liquid-liquid emulsion for PVC production in a full scale slim vessel. The numerical results are compared against experimental results  and the effect of different ways of decomposing the domain is discussed.
