ABSTRACT The energetics in the Bay of Bengal (BoB) region is influenced by primary and secondary mesoscale ocean processes, such as boundary currents, gyres, and eddies. Using the turbulent kinetic energy budget equation, the fluxes and their role in BoB dynamics are studied. A regional domain with a horizontal resolution of 0.1 is considered in the Indian Ocean, which includes the BoB region. The analysis of flow energetics reveals differences in eddy kinetic energy (K), shear production flux (P), buoyancy flux (B), and viscous dissipation (ε) terms. Our results reveal the presence of an inverse energy-cascade mechanism in the southern Bay of Bengal, wherein energy flows back into mean flow structures from the turbulent eddies. Further analysis shows that buoyancy flux, B, is the major source of turbulence production in the north and central BoB regions. These results define the mechanisms by which energy is produced and transferred in different regions in the Bay of Bengal.

ABSTRACT This paper reported on the free-surface wave behavior in a rectangular open-channel, induced by sluice-gate maneuvers. Numerical computations used the McCormack scheme to solve the one-dimensional extended St-Venant model embedding the Prandtl power-law momentum correction coefficient. The fundamental pulsation of the hydraulic system was inspected using the analogy with the water-hammer theory, known in pressurized-pipe flows. Different flow scenarios were reported; including the superposition between (i) downstream water-hammer maneuver and sine excitation of upstream flow depth and (ii) sinusoidal fluctuations of upstream lateral inflow and downstream flow-depth. Results highlighted that such sluice-gates maneuvers involved severe scenarios leading to significant amplifications of the depth peak and crest values above the initial value.

ABSTRACT Recently, coupling chaos theory with evolutionary algorithms (EAs) elevated further scope for improving EAs’ performance efficiency. In this view, the present study emphasizes investigating the influence of chaotic force on convergence properties of differential evolution (DE) algorithm in designing water distribution networks (WDNs). To this end, two novel chaos-directed DE models, Chaotic-DE and Chaotic-Fm-DE, are proposed. The Chaotic-DE model is formulated to enhance DE’s searchability and faster convergence by replacing every random phenomenon with a chaotic force. The Chaotic-Fm-DE model with a dynamic, chaotic mutation factor is developed to improve DE’s exploitation behavior. Essentially, these models differ from the previous chaos-directed EA models in how chaos ergodicity is simulated in DE mechanism. A novel scheme of non-sequential approach is used for this purpose. Further, their respective elitist models are formulated to promote the search in promising areas. Importantly, the elitism scheme developed saves the elite trial vectors to pass through the next generations. The results of proposed algorithms validated on five (new and rehabilitated) benchmark WDNs (whose dimensions vary from 8 to 454) demonstrate the enhanced search behavior of the chaotic models with solution precision and remarkable reduction in computational effort over the non-chaotic ones.
近年来，混沌理论与进化算法的耦合进一步提升了进化算法的性能效率。在此基础上，本研究着重研究了混沌力对配水网络设计中差分进化算法收敛特性的影响。为此，提出了两个新的混沌定向DE模型:Chaotic-DE和Chaotic-Fm-DE。混沌-DE模型通过将随机现象替换为混沌力来提高DE的可搜索性和更快的收敛速度。提出了一种带有动态混沌突变因子的混沌- fm -DE模型，以改善DE的开发行为。从本质上讲，这些模型与以前的混沌导向EA模型在如何模拟混沌遍历性方面有所不同。为此，采用了一种新颖的非顺序方法。进一步，建立了各自的精英模型，以促进在有前途的领域的搜索。重要的是，开发的精英化方案节省了精英试验载体的遗传给下一代。在5个(新的和修复的)基准wdn(其维数从8到454不等)上验证的结果表明，混沌模型的搜索行为增强，求解精度高，计算量显著减少。
