This paper deals with the detail of numerical modeling of turbulent flow over arbitrary sand.waves and their developing trends under tidal currents through a vertical two-D model without assumption of hydrostatic pressure. The test results show an obvious flow separation re:gion on the lee slope when the topography becomes steeper, with steepness 2a/ L=1/20 and maximum slope about 28°.The separation region extends 15m downstream, about 2.7 ti.mes of the waveheight, its maximum vertical extent is 2- 5m above...

This paper deals with the detail of numerical modeling of turbulent flow over arbitrary sand.waves and their developing trends under tidal currents through a vertical two-D model without assumption of hydrostatic pressure. The test results show an obvious flow separation re:gion on the lee slope when the topography becomes steeper, with steepness 2a/ L=1/20 and maximum slope about 28°.The separation region extends 15m downstream, about 2.7 ti.mes of the waveheight, its maximum vertical extent is 2- 5m above the bed, about 1/3 time of the waveheight and the maximum upstream current speed is 43 cm/s. The results also reveal that uneven distribution of hydrodynamic pressure P is the main mechanism causing flow separation on the lee slope. The sandwave developing trends under tidal currents is investigated by relation the caculated bed shear stress and velocity to the bed-load transport rate. It is found that sandwaves would become more symmetric in the areas of equal ebb and flood currents , while in the areas with currents dominated by one tidal stage, sand waves keep the asymmetric shape and advance in the direction of dominant flow.

应用垂向二维非静力假定湍流封闭模式,模拟任意沙波的湍流场以及双向水流作用下沙坡的运动趋势.数值试验结果表明,当沙坡坡度较大时,背水面和沙谷临底层存在明显的水流分离.分离区水平延伸距离为波高的2.7倍,垂向延伸距离为波高的1/3,最大反向流速为43cm/s.而水动压力分量分布的不均匀性是造成水流分离的主要动力机制.通过沙波推移质运移计算分析得出,当双向水流对称时,沙波具有向对称型演变的趋势;而水流非对称时,沙坡将保持原有的非对称形态,同时沿余流向迁移.

Both of processing and shielding formation are often fractured in one fracturing operation. There is a problem about real volume of fracture and the real volume of reduced fracture varied with the height of fracture in non-confined extension. The key factor of affecting the fracture to extend in vertical is the distribution of mainly minimum stress between formation.

Both of processing and shielding formation are often fractured in one fracturing operation. There is a problem about real volume of fracture and the real volume of reduced fracture varied with the height of fracture in non-confined extension. The key factor of affecting the fracture to extend in vertical is the distribution of mainly minimum stress between formation. The regular knowledge is acquired from making use of Terra-fare fully three-dimensional fracturing devise software and checking out the several typical minimum main stress affecting hydraulic fracture to extend in vertical. This is a great significance in this fracture device.

一次压裂往往能把处理层和遮挡层都给压开,因而就压裂的目的而言存在着裂缝的有效体积问题,裂缝的有效体积是随缝高的无限制扩展而减小的,影响裂缝垂向延伸的关键因素是层间最小主应力差的分布。利用TERRAPRAC全三维压裂设计软件考察了几种典型的最小主应力的纵向分布情况对水力裂缝扩展的影响,从中获得了一些规律性的认识,对压裂设计具有指导意义。

The Dongping-type gold deposits occur at the inner and outer contact zones of the Shuiquangou syenite complex, which locates to the south of the northern margin fault of the North China Craton. There are three types of ores in this type of deposits, pyrite-quartz vein type, pyrite - quartz - K-feldspar type, and pyrite- K -feldsparthized syenite type. The ore types vary from auriferous quartz vein at the upper part to silicified and K-feldsparthized syenite at the bottom of the ore bodies. The hydrothermal...

The Dongping-type gold deposits occur at the inner and outer contact zones of the Shuiquangou syenite complex, which locates to the south of the northern margin fault of the North China Craton. There are three types of ores in this type of deposits, pyrite-quartz vein type, pyrite - quartz - K-feldspar type, and pyrite- K -feldsparthized syenite type. The ore types vary from auriferous quartz vein at the upper part to silicified and K-feldsparthized syenite at the bottom of the ore bodies. The hydrothermal gold mineralization occurred in early Yanshanian Period, although the Shuiquangou syenite complex emplaced in Hercynian Period. The Pb, S, Si isotope and trace element investigations suggest that the principal ore forming material came from the syenite complex. The Pb isotopic compositions of the ores are similar to those of the syenite, as shown in the ~(207) Pb / ~(206)Pb -~(208)Pb / ~(206) Pb diagram, the ores, syenite, and Archean metamorphic rocks are linearly correlated and the ores are more closely related to the syenite than Archean metamorphic rocks do. Within a lateral transection profile that traversing a auriferous quartz vein, the contents of U and Th decrease as the K-feldsparthization and silicification increase, while the V_1 and V_2 have a similar variation trend with the exception of the samples near the auriferous vein. The V_1 and V_2 are pos- itively correlated to the elevation of the samples, where, hv_1 = 1 351 + 9. 3 V_1 with a correlation coefficient r = 0. 77; hv_2 = 1 222 + 17. 2 V_2, with r = 0. 92. Regarding the lead isotope data of gold deposits within the North China Craton,V_1 = -70 and V_2 = - 30 are taken as the lower limits of the Dongping-type deposits, and the maximum vertical extension of gold mineralization will be exceed 1 000 m. Thus, the gold exploration to the lower part of the gold mineralization should be reinforced in future exploration campaign.
