This study explores a novel flow control approach for enhancing the energy harvesting performance of an oscillating foil, which is promising technology renewable from wind and ocean currents. involves placing cylindrical spoiler structure at trailing edge foil investigating effects its diameter spacing on efficiency. The results show that cylinders can significantly increase efficiency by up to 19.26% compared case without them. optimal configuration found be 11.0% c in diameter, 0.5%...
The steady-state response and breathing mechanism of a cracked rotor supported by flexible bearings are investigated in this paper. generalized efficient method proposed paper can be used to study the dynamics complicated structures without much modification. First, three-dimensional finite element model rotor-bearing system is established rotating frame general contact for modeling crack proposed. A component mode synthesis form reduced-order model. Then, procedure combining multi-harmonic...
The effect of non-sinusoidal motion which influences the energy extraction performance foil is considered in this paper. Two oscillation motions, combined plunging and sinusoidal pitching motion, as well are selected to investigate process two-dimensional parallel foils numerically. optimal average power coefficient at different motions gained. effects analyzed, evolution law lift force vortex field obtained. It indicated that has a significant influence on extraction. When (non-sinusoidal...
Abstract In order to adapt the high-efficiency and low-resistance performances required by new generation of gas turbine, a type two-pass rectangular channel with cross bridge oval-shaped dimple structure is proposed for internal cooling blade mid chord region. Firstly, flow structure, heat transfer friction characteristics novel channels under stationary rotating conditions are numerically analyzed compared in detail. Then effects type/layout dimension/arrangement on performance discussed....
The oscillating foil energy extraction exhibits significant potential as a technology for harvesting renewable from both wind and ocean currents. study proposes novel flow control approach that utilizes cylindrical spoiler structure at the tail edge of to enhance performance. Specifically, research delves into effects diameter cylinder, well its transverse longitudinal spacing relative edge, on efficiency. Findings evince efficiency could be significantly augmented through incorporation...
