Special Issue Information

Dear Colleagues,

Computational fluid dynamics (CFDs) have been used for a wide range of applications, such as hydrodynamics, aerodynamics, water entry, water exit, multiphase flow, cavitating flow, turbulent flow, and fluid–solid interaction. However, there are still some challenges with regards to the complexity of physical problems, calculation accuracy, solution efficiency, etc. These challenges need to be addressed in order to provide a deeper understanding of physical problems. Hence, this Special Issue aims to cover novel, high-efficiency, high-precision, and appropriate CFD methods for the prediction and analysis surrounding the fluid dynamics problem in a variety of applications. Topics of interest include, but are not limited to, the following:

  • Computational fluid dynamics methods for hydrodynamics;
  • Computational fluid dynamics methods for aerodynamics;
  • Computational fluid dynamics methods for water entry;
  • Computational fluid dynamics methods for water exit;
  • Computational fluid dynamics methods for multiphase flow;
  • Computational fluid dynamics methods for cavitating flow;
  • Computational fluid dynamics methods for turbulent flow;
  • Computational fluid dynamics methods for fluid-solid interaction.

In hydraulic engineering, some researchers have developed different mathematical and numerical tools for a better understanding of the physical interaction between water flow in pipes with trapped air during emptying processes, where they have made contributions on the use of simple and complex models in different application cases. In this article, a comparative study of different experimental and numerical models existing in the literature for the analysis of trapped air in pressurised pipelines subjected to different scenarios of emptying processes is presented, where different authors have develope, experimental, one-dimensional mathematical and complex computational fluid dynamics (CFD) models (two-dimensional and three-dimensional) to understand the level of applicability of these models in different hydraulic scenarios, from the physical and computational point of view. In general, experimental, mathematical and CFD models had maximum Reynolds numbers ranging from 2670 to 20,467, and it was possible to identify that the mathematical models offered relevant numerical information in a short simulation time on the order of seconds. However, there are restrictions to visualise some complex hydraulic and thermodynamic phenomena that CFD models are able to illustrate in detail with a numerical resolution similar to the mathematical models, and these require simulation times of hours or days. From this research, it was concluded that the knowledge of the information offered by the different models can be useful to hydraulic engineers to identify physical and numerical elements present in the air–water interaction and computational conditions necessary for the development of models that help decision-making in the field of hydraulics of pressurised pipelines.
