Industrial CFD and Fluid Modelling in Engineering

Dear Colleagues,

In recent decades, computational fluid dynamics (CFD) and the formulation of increasingly performing numerical algorithms have allowed previously unexpected progress within the understanding of fluid motion. Despite this, dealing with realistic industrial problems through CFD approaches is still an incredibly challenging task. This is due to the geometric sophistication of the 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 if full-length simulations of realistic engineering devices have been successfully performed, the modeling assumptions underlying the achievement of the results are often a harbinger of doubt. 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 at the applicative side. However, by modeling all the scales of motion, this technique introduces heavy modeling hypotheses that must be carefully examined and verified a posteriori. On the other hand, more and more accurate methodologies are appearing, and the imminent horizon of the technique will see the time effect variations related to fluid motion as predominant aspects of the fluid dynamics analysis of industrial devices. This Special Issue intends to collect the best 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 system, fluid machinery). Moreover, the coupling of these techniques with optimization algorithms and operative research methods are of interest to the present volume. Authors are also 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 in the logic of greater efficiency and accuracy of results for 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.
