  1. A one - dimensional oceanic mixed layer model with the m - y level - 2. 5 turbulence closure schemes is employed. the rate of energy loss by breaking waves is estimated by parameterization and incorporated into the model as a source of turbulence kinetic energy ( tke ) by modifying the existing surface boundary condition of tke equation. the velocity field and turbulence energy budget are calculated under different forcing conditions ( the results given below are for a wind speed of 20 m / s. )

    採用一維2 . 5階湍封閉混合層模式，根據參數化方法對波浪破碎導致的能量耗散率進行了估計，通過改變湍動能方程的上邊界條件引入波浪破碎對湍動能生成的影響，計算了不同風應力強迫下的混合層流場結構和湍能量收支（下述給出的結果是取風速為20m s得到的） 。
  2. Results from this investigation show that the loss generation within the coolant holes is substantial and that ejection into regions of low static pressure increases the loss per unit coolant mass flow. the results also reveal strong interactions between endwall coolant ejection and secondary flow in the blade passage. the secondary flow has a strong influence on coolant trajectories and coolant ejection delays the three - dimensional separation of the inlet boundary layer on the endwall, chang the secondary flow and reduces its associated losses

    本文的研究成果顯示，冷卻孔內產生的損失是主要的，並且低靜壓區域的冷空氣噴射會增加單位冷空氣質量流的消耗；噴射的冷空氣與葉柵端壁流場之間有強烈的相互作用；二次流對冷卻空氣的流動軌跡有較強的影響；冷空氣噴射能延緩端壁入口邊界層的三維分離、改變二次流從而減少其相關損耗。
