The more favorable reservoir sandbodies are submerged distributary channel sandbodies and debouch bar sandbodies on delta front
較有利的儲集砂體為水下分流河道或河口壩砂體。 -
The main sedimentary microfacies are submerged distributary channel, debouch bar, submerged natural levee and flood - plain splay. the research shows that the physical property of subermerged distributary channel sandbodies are the best and debouch bar comes second
長4 + 52長62油層砂體的沉積微相類型主要有水下分流河道、河口壩、水下天然堤和水下決口扇等,其中水下分流河道砂體的物性相對最好,其次為河口壩砂體。 -
This paper described a cold gas simulation of solid rocket motor with submerged nozzle. a two - dimension model with rectangular channel was designed, which can simulate different flow conditions at three periods after ignition
本文從冷流模擬的角度出發,設計了通道為矩形的含潛入噴管發動機冷流模型,可以模擬發動機工作過程中三個不同時刻的流動狀態。 -
Applying the proposed model, the turbulent flow in open channel with submerged vegetation has been simulated and the flow effect due to vegetation has been analyzed
應用該模型進行了存在淹沒植物的河道水流紊流運動數值計算研究,分析了淹沒植物對河道水流的影響。 -
This paper describes the application of semi - circular breakwater at home and abroad and the design innovation and optimization of semi - circular jetty in yangtze estuary deepwater channel regulation project, esp. the design of estuary jetty structure using semi - circular floating caissons ; a new calculation method for wave forces acting on the submerged semi - circular estuary jetty and the optimization design method for semi - circular structures are recommended
摘要介紹半圓型防波堤和河口導堤在國內外的應用概況及在長江口深水航道治理工程中對半圓型導堤的設計創新和優化半圓型浮式沉箱的導堤結構型式,提出堤頂淹沒情況下半圓型導堤波浪力的計算方法以及半圓型結構的優化設計方法等。 -
At the preliminary stage of burning the gas flows along the back surface of the submerged nozzle and no recirculation forms in the aft - end cavity. at the medium stage of burning a weak recirculation forms in the rear of aft - end cavity by the force of injection flow. at the end stage of burning the flow separates at the c ombustion channel and a strong vortex forms in the aft - end cavity
實驗結果表明,在發動機工作過程中隨著燃面的退移,燃燒室尾部的流動會發生很大變化,初始時刻背壁區加質流沿噴管背壁進入噴管,背壁區沒有迴流形成;中間時刻在加質流的驅動下背壁區後部形成較弱的迴流;結束時刻氣流在燃燒室壁面分離,背壁區形成強烈的迴流。
