Physics of Fluids, Год журнала: 2024, Номер 36(11)

Опубликована: Ноя. 1, 2024

Although scaled physical models and numerical simulations have been employed to study the hydrodynamic performance of recirculating aquaculture system (RAS) tanks, there remains a paucity prototype experiments that fully reflect actual performance. In this study, experiment was conducted on RAS utilizing advanced image processing techniques specifically adapted scale. This focused impacts various jet inflow parameters, including angle (0°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70°), rate (150, 180, 210, 240 l·min−1), area (942 1884 mm2), location (curved wall straight wall), waste removal efficiency tanks. The results demonstrated performance—specifically average flow velocity, field uniformity, extent low-velocity zones conjointly determining efficiency. curved proved be optimal for pipe placement, while 45° yielded best balance between optimization Furthermore, reducing inlet significantly improved velocity whereas variations in had minimal impact these factors. Supported by compelling findings, offers theoretical insight practical guidance achieving efficient RAS, thereby contributing advancement sustainable practices.

Numerical analyses of water swirls in aquaculture tanks

Physics of Fluids, Год журнала: 2024, Номер 36(7)

Опубликована: Июль 1, 2024

Water swirls were observed in both model and prototype aquaculture tanks with bottom drains. This phenomenon was seldom replicated studies of flow fields water computational fluid dynamics. A commonality these is that the linear eddy-viscosity turbulence models employed. study delves into from aspect generation kinetic energy; nonlinear are used, as well a Reynolds stress model. novel identification method utilized to pinpoint vortex structures. Numerical results affirm outstanding performance estimate tanks. Both overestimate energy stagnation zone swirls. The overestimation can be restrained by including effect streamline curvature correction (SCC) production term. Even so, SCC does not help improve estimating accuracy between tensor mean rate-of-strain tensor. While offers some improvements, provides more effectvie solution. After that, we calculate different inlet–outlet configurations vertical horizontal scales increase inlet velocities Froude numbers, where number based on draining velocity depth above drain. distributions residence time shown design
