Computational fluid dynamics (CFD) has been extensively used for fluid flow simulation and thus, guiding the flow control device design. However, CFD simulation requires explicit geometry input and complicated solver setup, which is a barrier in case of the cyclic CAD/CFD integrated design process. So far, tedious human interventions are inevitable to fill the gap. To fix this issue, this research proposes a theoretical framework where the CFD solver setup can be intelligently assisted by the simulation intent capture. Five innovative feature concepts are proposed. The fluid functional feature is used to capture the design intent while the fluid physics feature and dynamic physics feature present the simulation intent. The inter-feature associations are established by CAE boundary features and effect features. These feature concepts are defined based on the need of CAD/CFD integration and intelligent CFD solver functions for steam simulation. A prototype software tool has been developed for intelligent CAD/CFD integration, where the design intent and CFD simulation intent are associated seamlessly. An outflow control device (OCD) model, used in the steam assisted gravity drainage (SAGD) process, is studied by applying this prototype, and the target performance of this design is effectively reflected and virtually improved. The optimization result is further validated by a realistic OCD model from the industry, which confirms the software tool can provide design guidance for better steam even distribution. Therefore, it proves that the proposed method is capable of supporting complex design optimization in practice.
