Abstract Marine transportation is still the primary source of global transportation. The propeller, which a critical componentof propulsion system, must be designed with multiple constraints and objectives to satisfy need. Recent studies propose that utilizing an improved optimization algorithm computational analysis would explore better designs than conventionalmethods. In present study, Elitist Particle Swarm Optimization (EPSO) technique implemented optimize design ofa marine propeller. Potsdam’s Conventional Propeller VP 1304 used as benchmark case. Reynold’s Averaged NavierStokes equation based Computational Fluid Dynamics (CFD) along Vortex Lattice Method (VLM) StructureInteraction (FSI) model for analysis. results obtained in this study are validated against previously published experimental data. An optimized propeller proposed on technique.It observed shows open water performance lower advance coefficient (J) valuesbased given constraints. It’s also efficiency by 7 percent J=0.6 compared tothe original design. one-way Structure Interaction structurally stable underopen test conditions

Water pollution has become a major environmental menace due to municipal and industrial effluents discharged into water bodies. Several processes have been devised for the treatment disposal of wastewater sludge. Yet, most conventional technologies do not meet requirements sustainability as they impose higher load on environment in terms resource depletion toxic waste generation. Recently, sustainable innovative technologies, like hydrodynamic cavitation (HC), emerged energy-efficient methods, which can enhance processes. HC is very effective technique intensification processes, aeration, activated sludge treatment, anaerobic digestion plants, particularly enhanced degradation persistent pollutants. On other hand, advanced oxidation proven enhancement method treatment. This review provides comprehensive overview recently published literature application organic The potential synergistic impact coupled with alternative pre-treatment methods was also reviewed this study. Moreover, an present state model-based research work reactors feasibility analysis various process covered. Options pilot-to-large scale implementation ensure better plants are recommended.

The occurrence of cavitation in marine propellers is a major source noise ships. Consequently, the and characteristics must be better understood to control this issue. This study focuses on identifying cavitating flow around two-dimensional (2D) hydrofoils. Using commercial computational fluid dynamics software STAR-CCM+, numerical analysis was conducted partial cavity occurring 2D hydrofoils at specific angles attack. In addition, were analyzed by conducting frequency using predicted pressure data obtained via fluctuating sensor positioned vertically above hydrofoil. results compared with existing experimental validate accuracy simulation. identifies limitations Reynolds-averaged Navier–Stokes (RANS) method closely comparing it large eddy simulation (LES) for assessing unsteady flow. Although RANS has qualitatively periodic behavior LES, effectively predicts extent valuable relative assessments practical applications.
