  1. Another man-made effect is the generation of mechanical turbulence caused by the nonuniform height of buildings in a city.

    由於城市建築物高度不一致而引起的機械湍流是另一種人為的影響。
  2. It is studied that the formation mechanism of taylor bubble and its control method in gas - liquid two - phase flow, which affects the pressure balance and mechanical driving efficiency in the flow of petroleum engineering. experiments show that the formation of taylor bubble in gas - liquid two - phase flow is due to the intensive congregation and amalgamation of small bubbles driven by void fraction waves and that the highly turbulent flow is able to restrain this formation. thus, the flow regime transition may be checked by increasing the flow turbulence and controlling the disturbed frequency

    對大管徑氣-液兩相流動中嚴重影響壓力平衡與機械驅動效率的段塞流生成機制和控制方法進行了研究，實驗證明段塞流的形成是由於空隙率波的大幅度增長使氣泡高度集中，並形成聚並所致。強湍流運動可以抑制taylor泡的形成。因此，通過強化湍流或控制擾動頻率可以對氣泡聚並起明顯的抑制作用。
  3. A brief of description of the fluid machinery development, turbulence and computational fluid dynamics ( cfd ) in the engineering is introduced

    簡要介紹了流體機械設計方法、湍流和計算流體力學的發展狀況及在工程中的應用； 2
  4. Internal waves are a kind of bridge relating the diapycnal mechanical mixing to external sources of mechanical energy : first, internal waves are driven by wind stress and barotropic tide so that large amount of mechanical energy are transported to abyssal ocean with propagation of internal waves ; second, the mechanical energy can directly be cascaded to mixing through instability and breaking of internal waves

    內波是外界提供的機械能與混合之間聯系的橋梁之一，一方面風和潮汐通過激發內波，將能量向深海和大洋內區傳遞，另一方面，內波的不穩定和破碎直接將機械能串級到小尺度湍流混合中去。開展傾斜地形上內波的傳播以及內潮的產生等方面的研究對海洋混合過程的參數化以及混合對大洋環流的影響等方面的研究具有重要的科學意義。
  5. Based on former work, a finite difference viscous code that uses a high convergence, high accuracy, high resolution lu - sgs - ge implicit scheme and an improved fourth ( fifth ) - order high resolution muscl tvd scheme to integrate the full 3d navier - stokes equations and the low - reynolds number two - equation turbulence model is extended to simulate the flow field inside centrifugal impeller mechanism

    並且在現有工作基礎之上，將基於有限差分方法的高收斂率、高精度、高解析度的lu - sgs - ge隱式格式和四（五）階muscltvd格式求解全三維navier - stokes方程和低雷諾數雙方程湍流模型的計算程序推廣到離心葉輪機械內部流場的數值求解。
  6. With the rapid development of numerical technology and cfd simulation, the numerical technology for the forward problem of impeller machinery design had a good investigation and application, but the turbulence model need to be improved

    由於計算流體力學和計算技術的迅速發展，利用數值技術進行流體機械正問題研究已經較為成熟，並有一定的研究與應用，但湍流模型尚待進一步完善。
  7. The ocean circulation is controlled by diapycnal mixing which consists of mechanical mixing and convective mixing. the intensity of mechanical mixing depends on the amount of mechanical energy offered by external processes, among which wind stress and tidal generation force are major sources

    海洋中的湍混合包括機械混合和對流混合，混合的強弱是控制大洋環流的重要因素，其中機械混合的強弱取決于外界機械能的供給，風和潮汐是重要的機械能之源。
