The natural ventilation efficiencies of the leeward and side rooms can be improved when the hot pressure is increased. 但增加了热压作用后,可明显改善庭院式建筑背风面和侧面房间的自然透风效果;
Sandhills on the leeward side of the island dene: a sandy tract or dune by the seashore. 该岛下风处的沙丘.沙丘:海边的沙地或沙丘。
The aerodynamic shadow zone means an area of vortex caused by wing field, which lies in the leeward side and the top of building. 空气动力阴影区是在风的作用下建筑物背风侧和顶部的旋涡区。
Typically, a bridge structure should be examined separately under wind pressures from two or more different directions in order to ascertain those windward, leeward, and side pressures producing the most critical loads on the structure. 典型的情况是,为了确定对结构产生最危险荷载的上、下风向及侧向压力,应分别地在来自两个或更多方向的风压作用下,分析一座桥梁结构。
Application of several k-ε models to the calculation of separated flows on the leeward side of slender body 几种k-ε模式在细长体分离流计算中的应用
The three aerostatic coefficients are larger when the train is on leeward side of deck than on windward side of deck, the lift coefficients and pitch coefficients of girder are raised when train passing though the bridge but the drag coefficients are reduced. 列车在下风侧时的桁梁三分力系数较列车在上风侧时大;列车在桥上运行时,会增大桁梁的升力系数和力矩系数,降低桁梁的阻力系数。
In the case of angle of attacks, the high pressure region before the leeward side jet enlarged, the region of jet wraparound effect moving forward, and the jet interaction control was more effective. 有攻角时,背风侧喷流前的高压区更大,喷流包裹作用的影响区域前移,喷流的控制效果更好,这一趋势随攻角的增大更加明显。
Experimental investigation of the lateral jet interaction have been performed in supersonic flows to study the effects of jet pressures, angle of attacks, leeward side jet or windward side jet on the jet interaction characteristics. 在超音速流动中,进行了侧向喷流干扰特性的实验研究,研究了喷流压力、攻角、迎风侧及背风侧喷流对侧向喷流干扰特性的影响。
Numerical study on the leeward side orographic effects of Qinghai-Xizang Plateau on a Southwest Vortex process 青藏高原背风坡地形对西南涡过程影响的数值试验
The results show that the concentration of pollutants in leeward side is much higher than that in the windward side in street canyon. Therefore, the pedestrians and bicyclists in the leeward side suffered more serious emissions. 研究发现在街道峡谷中,背风侧的污染物浓度远远高于迎风侧的污染物浓度,因此,在背风侧的步行及非机动车出行者所受机动车排放尾气的影响较为严重。
Compare the mean aerodynamic force coefficient of the train which is on the windward side, leeward side and parallel condition in different beam heights in the train-bridge system, assess the traffic safety when the train running in the different position. 4. 比较了车-桥系统中不同梁高情况下列车位于迎风面、背风面、并行时的三分力系数,评估了列车不同运行位置情况下列车的行车安全性。
The soil water content in most leeward side of fixed and semi-fixed dunes were higher than those in windward side, however, moving dunes were just the opposite. 固定和半固定沙丘的大部分背风面的含水量比迎风面的含水量高,而流动沙丘却恰恰相反。
