An object-oriented approach to hybrid CFD/multizonal modelling

Abstract

Process simulation and Computational Fluid Dynamics (CFD) are well-established tools in the process industry. The two technology are largely complementary and their combined application can lead to significant industrial benefits. In view of the advantages and limitations of process simulation and CFD modelling, it is natural to consider hybrid approaches that attempt to combine the two. This may bring great advantages in the process and product design, in the equipment scaling up and down, in the capability of optimising the process and delivering solid technical criteria for business decision making. A few works have recently appeared demonstrating the feasibility of a combined approach where critical parameters are exchanged between a CFD and a process simulation model. In this paper a novel design for hybrid CFD/multizonal modelling is considered in terms of an object oriented approach. This generic modelling approach allows an easy-to-use and effective representation of the process by a synergic use of available technologies.
