Piezoelectric materials can be used to harvest ocean wave energy by directly converting wave energy into electrical energy. Combining piezoelectric membranes with flexible membranes to form a submerged breakwater structure can serve as a new type of wave energy conversion device, possessing the dual…
The dispersion and polarization characteristics of Scholte waves excited by sound sources in shallow water are of great significance for target detection; however, current understanding of Scholte waves excited by pulsed and continuous point sources remains insufficient. This study investigates the …
Thermal stratification is one of the primary causes of thermal fatigue failure in the piping systems of pressurized water reactors (PWRs). This study aims to investigate the transient thermal distribution characteristics of piping structures caused by thermal stratification in reactor configurations…
The hydrodynamics of flow around pile groups beneath pile-supported wharfs is more complex than that of single-pile structures and exerts significant influence on harbor hydrodynamics and sediment transport. To investigate the underlying interaction mechanisms, a laminar flow model based on the CFD …
Currently, water hammer numerical models commonly employed in hydraulic engineering often neglect the influence of cavitation induced by negative pressure, with most friction models still utilizing steady friction models, namely the Darcy-Weisbach formula, resulting in simulation results that undere…
Focusing on shock wave boundary layer interaction phenomena in inlet isolators, this study systematically compares the capabilities of shock relation method, Euler method, RANS method, DDES method, etc., in predicting shock train structures and wall fluctuating pressure, and conducts back-to-back va…
Linear vibrating screens and translational elliptical vibrating screens represent two developmental forms of drilling fluid vibrating screens. Investigating the screening efficiency of these two vibration modes under different operating parameters holds value and significance for practical productio…
Mesh is the foundation of computational fluid dynamics (CFD) numerical simulation. To investigate the applicability of different mesh types to gas dispersion simulation in chemical industrial parks, full-scale numerical simulations were carried out based on field leakage experiments of tracer gas (S…
Rectangular frame-type artificial reefs can be employed to modify flow fields, providing favorable habitats for various marine organisms. In tropical marine areas such as the offshore waters of Hainan Island, they can also serve as attachment substrates for coral restoration. Flow velocities at repr…
