Complex flows are commonplace in engineering systems and the temptation to model flow regimes in their most general three-dimensional (3D) and time-variant detail seems difficult to resist. However there may be quicker, more cost-effective ways using 1D or 2D simulations, for example, to meet project objectives, and, if this is possible, the project workflow would certainly benefit from early results and reduced analysis costs. With the appropriate decisions and simulation tools, analysis quality and accuracy may even be further enhanced.

sentations focus on industrial case studies showing what using CFD brings to a project that cannot be achieved using other methods. For example, CFD can really help in understanding flow behaviour since testing flow systems and taking measurements from them (without affecting the flow) is problematic.

Flow simulations are used in almost all sectors with many different applications and methodologies so different sectors and applications have been encouraged in order to create awareness and enhance our inter-sector discussion, collaboration and learning.
