It is, therefore, necessary that engineering students have a good understanding of the concepts behind the design and use of fluid flow systems. Although theory is absolutely necessary to understand real‐life problems involving fluids, experiments form an excellent supplement to provide students with opportunities for visual appreciation of the complexity of flow phenomena, allowing such knowledge to be less abstract. However, the ever increasing challenge of designing more efficient engineering systems that address environmental concerns, and energy demand, requires students to have access to additional tools. While experimental data are useful for specific scenarios, engineering design of fluid flow systems often require sets of iterative calculations in which a design is tested under different conditions of operation. A cost‐effective solution is the use of computational fluid dynamics (CFD) simulations. CFD is a fast growing branch of fluid mechanics, in which one seeks solutions of mathematical models of physical systems by numerical integration of the governing equations. In this contribution, we present an approach that combines CFD analysis with laboratory experiments, to supplement the traditional teaching method based on a theoretical approach, with the aim to provide a well‐rounded experience for the students to learn and apply fluid mechanics concepts in the design of engineering systems. The integration of theory, physical experiments, and mathematical/numerical models is done via an open source CFD system, called OpenFoam. The OpenFoam software, grounded on finite volumes technique, will be linked to an educational interactive flow visualization set comprised of two systems: (FLOWCOACH and ePIV, currently used to provide students with opportunities for visual appreciation of the of flow phenomena. A main advantage of using OpenFoam is that building the geometry and setting the boundary and initial conditions is straightforward. Assessment of the accuracy of the OpenFoam scheme is carried out by direct comparison of for the solution to two fluid‐flow problems; named, flow around a square obstruction and flow in an divergent channel, against two well‐known CFD software: Gerrys and COMSOL Multiphysics.
