渦旋消失
英文
dissipation of vorticity-
After simulating the model of water hydraulic valves, the velocity distribution, pressure distribution, energy distribution can be obtained and relations between the valve channel and the energy loss, the negative pressure distribution can be analyzed, which offers the theory foundation for designing water hydraulic valves with the high efficiency, low energy loss and low noise
通過對水壓閥模型的cfd穩態和瞬態解析,可以得到水壓閥內流場的速度分佈、壓力分佈及能量分佈,據此定性分析流道結構(速度、壓力、流動的分離與再附壁,旋渦的產生與消失等)與能量損失、負壓分佈等的關系,從而為設計出高效率、低能耗、低噪聲的水壓閥提供理論依據。The 3d simulation result shows characteristics as well as creating, developing and dissipation process of the microjet. the results show good agreement with experimental results. the numerical study reveals the spanwise instability of vortex pairs, resulting in the breakdown of the coherent vortex structure
三維微射流流場的數值模擬再現了實驗所觀察到的旋渦對的生成、發展及其相干性的消失過程;揭示了旋渦對沿展向的不穩定性是旋渦對相干性消失的主要原因。
