Special Issue Information

Dear Colleagues,

The modeling and optimization of hydrodynamic and aerodynamic flow processes are key issues in fluid dynamics research and are widely applied across many fields, including process equipment, aerospace, marine vessels, energy and power engineering, and environmental engineering. At present, with the rapid development of computer technology and numerical algorithms, traditional modeling methods based on simplified assumptions are gradually being replaced by high-precision, multi-scale numerical simulation techniques. For example, turbulence simulation technology, which has been rapidly advancing, enables precise capture of the evolution of flow fields. Emerging technologies such as fluid structure coupling modeling and multiphase flow modeling have gradually become research hotspots. The flow control and optimization methods based on artificial intelligence and machine learning have emerged as a novel approach, with stronger capabilities in mechanism discovery, becoming more efficient and intelligent means of evaluation and optimization design.

This Special Issue on “Modeling and Optimization of Hydrodynamic and Aerodynamic Flow Processes” seeks high-quality papers that focus on the development and application of modeling and optimization methods for flow processes. Topics include, but are not limited to, methods and applications in the following areas:

  • High fidelity modeling methods and applications for hydrodynamic and aerodynamic flow processes;
  • Refined experimental measurement techniques for flow processes;
  • High-fidelity digital twin technologies for flow processes;
  • Modeling methods for multiphase flows and flow interface evolution;
  • Artificial intelligence-based modeling and prediction methods for flow processes;
  • Data-driven approaches for flow feature extraction;
  • Adjoint theory-based optimization methods for flow processes;
  • Multi-field coupling modeling and optimization methods in flow processes;
  • Application of flow process modeling and optimization methods in sustainable development;
  • Innovations in aerodynamics/hydrodynamics for low-carbon aviation, green ships, and energy-saving equipment.

Loading fluctuations cause structural responses such as deformations and vibrations on the propeller. Structural response of propellers results in vibrations on the shaft system or even the hull. Considering the demand for structural safety, the correlation between structural response of propellers and inflow conditions is numerically studied in the present paper. The interaction between the propeller and turbulence structures and vortex shedding from upstream structures is considered. Loading fluctuations on the propeller blade are obtained by a turbulence model of improved delayed detached eddy simulations (IDDESs). The deformations and vibrations of propeller blades fixed at their roots are captured considering fluid–structure interaction. Results show that the loading fluctuations and vibrations on the propeller contain tonal components occurring at harmonics of shaft frequency and broadband components. Inhomogeneous inflow amplifies pressure fluctuations as a product of space frequency and shaft frequency (SF). Inhomogeneous inflow also results in more intense fluctuations of velocity in the tip vortex at SF and blade wake at blade passing frequency and encounter frequency. As a result of loading fluctuations, the vibration of the blade is a superposition of excited vibrations and natural vibrations. Inhomogeneous inflow amplifies the vibrations at the encounter frequency. Resonance of the blade can be observed when the excited frequency approaches the first natural frequency. Full article
