DEVELOPMENT OF THE KARMAN VORTEX STREET DUE TO THE NATURAL CONVECTION
Investigation in the present paper has been made theoretically and experimentally on a development of the Karman vortex street due to the natural convection in an opposing flow. Unsteady numerical solutions are obtained by means of a time-dependent numerical analysis.

CFD‐Assisted Spray Decontamination Process Assessment for Nuclear Tank Decommissioning
The decontamination of high‐level radioactive nuclear storage tanks with complex internal devices poses critical challenges in nuclear decommissioning engineering. This study develops a computational fluid dynamics (CFD) framework integrating the volume of fluid–discrete phase model (VOF–DPM) with the Eulerian wall film model (EWFM) to systematically ...

Extrapolation Boundary Conditions for 2‐D Smoothed Particle Hydrodynamics
This paper introduces novel inflow, outflow, and wall boundaries for the WCSPH method. Utilising innovative concepts from finite volume methods, fluid properties of sequential dynamic particles with varying distances to boundaries are extrapolated to ghost and wall particles using first‐order Taylor series expansion.

Integrated Turbulence and Machine Learning Models Explain Pier Scour in Erodible Channels
Abstract Pier scour, a primary cause of bridge failures, stems from turbulent erosion at the pier's approach surface, jeopardizing bridge stability and influencing both river morphology and interactions between aquatic and terrestrial ecosystems. The scouring process, initiated by turbulent eddies interacting with sediments over erodible channels ...

A Turbulence Model for Velocity Distribution in Open‐Channel Flows Through Mangrove Trees
Abstract The vertical distribution of flow velocity plays a critical role in sediment transport and nutrient circulation within mangrove forests, characterized by their intricate root structures. Existing velocity profile models typically rely on a single mixing length scale, limiting their ability to capture the energy distribution of turbulent eddies
