Industrial CFD and Fluid Modelling in Engineering, 2nd Edition

Dear Colleagues,

Over the last few decades, computational fluid dynamics (CFD) and the formulation of advancing numerical algorithms have led to previously unexpected progress in understanding fluid motion. Despite this, dealing with realistic industrial problems through CFD approaches is still incredibly challenging. This is due to the geometric sophistication of industrial reality and the complexity of the flow topology involved in applications, as well as the computing powers needed to carry out full-scale simulations. In addition, even though full-length simulations of realistic engineering devices have been successfully performed, the underlying modeling assumptions often cause issues. In the industrial context, the Reynolds average Navier–Stokes (RANS) approach has shown great flexibility, and today, it can be considered the leading and top-rated strategy. However, by modeling all scales of motion, this technique introduces heavy modeling hypotheses that must be carefully examined and verified a posteriori. On the other hand, more accurate methodologies are being developed, and one imminent technique will use time-effect variations related to fluid motion as core parameters for analyzing the fluid dynamics of industrial devices. This Special Issue intends to collect the foremost ideas concerning the modeling of industrial flows. Ample space will be reserved for validating RANS techniques in real applicative geometries (e.g., aerodynamical components, turbomachinery, conversion energy systems, fluid machinery). Moreover, the coupling of these techniques with optimization algorithms and operative research methods is also of interest. Authors are invited to contribute through innovative ideas concerning fluid modeling, such as contributions to the formulation of new turbulence models, novel approaches for wall-bounded flows and, in general, new CFD paradigms. These may include the formulation of innovative algorithms or the coupling of existing techniques with a view to formulating new paradigms for greater efficiency and more accurate results in industrial computational fluid dynamics.

Thus, the potential topics of the present Special Issue include, but are not limited to, the following:

1. Large/detached eddy simulations;
2. RANS modeling validation;
3. Optimization strategies;
4. Aerodynamics and turbomachinery modeling;
5. Super/hypersonic flows;
6. Multiphase and reactive flows.
