The variation of the negative / positive value of the baroclinc potential vorticity under 850hpa has a very good corres pondence with the development of the cyclone
850hpa以下的斜壓位渦的正負值的變化與氣旋的發展有很好的對應關系。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。
