Special Issue Information

Dear Colleagues,

In the present Special Issue, we aim to collect pioneering research studies toward modelling-induced waves by floating structures mathematically and experimentally. The scope covers hydrodynamic modelling of fluid flow around marine structures and evaluation of the performance of marine structures. Parametric geometrical modelling (CAD/CAM) and geometry optimization using artificial intelligent algorithms will be appreciated in this Special Issue. Moreover, the development of computational codes with high fidelity in hydrodynamic analysis of marine structures is in the scope, as is the application of top-notch computer programming into the computational code. Our goal is to gather hydrodynamic models which take advantage of advanced techniques in computational fluid dynamics. Moreover, advanced potential flow models are of interest in this Special Issue.

In the marine fire suppression system, continuous delivery of dry chemical powder to the fire source with long powder discharge range and high dispersion concentration is essential. The work is devoted to experimental and numerical studies of the flow characteristics of the dry chemical powder jet from a horizontal injector with a wide range of Stokes numbers between 6 to 30 and Reynolds numbers between 4792 to 23,960 by considering the effect of gravitational acceleration. A CFD-based Eulerian–Eulerian multiphase model combined with Standard k-ω turbulence model was used to predict flow characteristics of particle-laden jet using dimensionless numbers, including the solid volume fraction, the normalized velocity magnitude, and the turbulent viscosity ratio. Experimental studies have been carried out for three different inflow velocities (2.06, 2.45, and 2.81 m/s). The results indicate that the particle density plays a significant role in the dispersion of the particles in the radial and axial directions. The transition from U-shaped to V-shaped solid dispersion structure on the ground can be captured with the increase of particle density. Moreover, the higher level turbulence intensity enhances the solid dispersion concentration. Finally, it was found that the Portland cement powder exhibits better discharge performance in terms of solid discharge range and dispersion concentration in comparison with other dry powders. These results have implications in the design of powder-based fire suppression system. Further studies should aim to the in-depth research on the fire extinguishing mechanism of the Portland cement powder, especially the fire suppression effectiveness and thermal decomposition process.
