Abstract The draft tube of a hydraulic turbine plays an important role for the efficiency and power characteristics overall system. shape affects its performance, resulting in increasing need data-driven optimisation design. In this paper, elbow-type is undertaken, combining Computational Fluid Dynamics multi-objective Bayesian methodology. chosen design objectives were to maximise pressure rec...

The installation of new and revitalization existing hydropower requires the optimal design hydraulic turbine parts, which were previously mostly based on simplified analytical methods engineering practices. With increase in computational power, optimization now present an effective approach to improvement geometry thus enabling fine geometry-tuning adjustments site specifics. However, despite c...

Pumped storage hydropower plants are renewable energy systems that effective in saving and solving electricity peak-on shortage. Seawater pumped a novel type of plant specifically supplying electric power for ocean islands with the support solar wind energy. Compared traditional constructed on mainland, seawater should take influence complex marine environment, such as extreme waves winds, into...
