Domain Geometry and Process Models
Publication: Computational Fluid Dynamics Modeling in Water Infrastructure: Best Practices
Abstract
Problem formulation is the first major step when building and executing a CFD model. This step consists of formulation of goals and expectations, definition of the geometry, and understanding of process models and temporal scales involved. A detailed, yet succinct description of the key elements associated with problem formulation, model domain, selection of process models and CFD software needed when building a CFD is provided. During the problem formulation phase the CFD modeler should seek to clearly state the objective, domain geometry, operating conditions, dimensionality of the mesh, appropriate temporal modeling technique, simulation time span required to properly model the flow phenomena, number of fluid phases and constituents, and viscous nature of the flow. Physical, chemical, and biological processes may be involved alone or in combination in water related problems. The main subprocesses associated with each of such processes typically available in CFD modeling today are listed.
