查询词典 fluid

Firstly, the natural frequencies and normal mode shapes of the fluid-conveying pipe with zero fluid velocity (i.e. U=0) were determined with the transfer matrix method. Next, these natural frequencies and normal mode shapes were used to derive the equation of motion for the fluid-conveying pipe with fluid velocity U.neq.0 by using the expansion theorem. Finally, the free and forced vibration responses of the pipe with flowing fluid were obtained by means of the Jacobi method and the Newmark direct integration method.

首先吾人使用转移矩阵法来求取一流速等於零(即U=0)、跨距数为N之流体输送管的自然频率及其所对应之正规化振态，然后利用振态重叠法原理来推导流速不等於零(即U.neq.0)时，整个流体输送管在外力作用下的运动方程式，最后再以Jacobi法及Newmark直接积分法来计算该水平流体输送管的自然频率及强迫振动反应。

In the proposed formulation, the fluid jump arc of Second order Fluid Stochastic Petri nets, which takes deterministic jump height, is introduced for the sake of modeling impulse rewards. In order to model non-Markovian stochastic systems, the fluid jump arc is combined with the flush-out arc. As a result the fluid jump arc as a modeling primitive has the function of emptying in zero time the existing fluid from the continuous place connected with it.

Body fluid bears two physiological functions: moistening and nourishing:body fluid distributed to the body surface moistens and nourishes the muscles and skin with hairs; body fluid permeated through the body orifices moistens and protects the eyes, nose,mouth and other openings; body fluid infiltrated into the blood vessels nourishes and smooths them and is also the basic component of blood; body fluid poured into the internal organs nourishes and moistens them, and body fluid in the bone nourishes and moistens the bone marrow, spinal cord and brain marrow.

津液有两种生理功能：滋润和营养。津液分布于肌表滋养肌肤毛发；渗透于体窍滋润和保护眼、鼻、嘴和其它官窍；津液渗透至脉管起到营养和滑利的作用，也是血液的基本组成成分；津液注入内脏使其得到滋养；骨中的津液对骨髓、脊髓和脑髓起到滋养作用。

The geology research of carbonate reservoirs in Ordovician of Tahe oilfield showed that many large dissolved vugs and fractures were developed. The spread of the reservoir take on a very heterogeneous state. And the typical fractured-vuggy reservoirs was formed. According to the combination of the various spaces, the formation was divided into vuggy formation, fractured-vuggy formation and fractured formation. The research showed that development of the vug is relevant to the its position on the structure, the fractures, the water surface and the weathering surface. Multi-phase charge and recharge of the oil in the reservoirs resulted in the complexity of the fluid distribution. So the"Bottle Model"was brought forward to explain the movement of the water-oil contact. The special storage space and the complex fluid distribution lead to the unstability of the production and the complexity of the water cut. In order to explain the characteristic of the fracture-vug unit was brought forward and the basic principle and method of the partition of the fracture-vug unit was formed. The classification and evaluation of the units were performed according the reserve and energy. Based on the research of geology characteristic and the fluid flow in the reservoir the comprehensive numerical simulation plan of the fractured-vuggy reservoirs were established. Through the selection of the simulation unit, fluid flow type and parameter equivalent the triple media reservoir simulation model was established. Considering the practical application the model was resolved by the DKR decomposition conjugate grads method. Based on the fine reservoir description of Dsitrict IV of the Tahe oilfield the various space type were classified and combined together. The geology model of Unit S48 was constructed. Two typical single well model was established according to the geology and the dynamic phenomena. Finally the single well model and the Unit S48 were simulated by the triple media reservoir simulator. Via the local grid refinement and coarsening in the simulation good matchs were gained. Based on the results of the simulation the reserve distribution, percent of reserve produced in various space and the natural energy were analyzed. The fluid was storaged in the fractures and vugs mostly and more than 90% the produced oil came from the systems. The energy belonged to the active one. The results of simulation accorded with the fact and showed the validity and practicability the research and the simulator.

Experiment results indicate that the magnetic fluid flux has a direct relation with the magnetic field under the effect of traveling wave magnetic field. The bigger the magnetic field is, the more the flux is, when the structure of the magnetic fluid travellig pump and the saturation magnetization of magnetic fluid are constant. The volumes of the magnetic fluid from the travelling wave pump increase from 1.9 ml to 3.1 ml, when the magnetic field intensity increases from 25 900 A/m to 40 000 A/m. In addition, the change rate of the magnetic fluid decreases with the increase of the magnetic field due to the effect of magnetic field on magnetic fluid viscosity. The bigger the saturation magnetization of the magnetic fluid is, the more the flux is.

结果表明，行波磁场作用下的磁性流体流量与磁场的强度有直接关系：在磁性流体行波泵结构和磁性流体饱和磁化强度相同的条件下，磁场强度越强，其流量越大；当磁场强度从25900A/m增加到40000A/m时，单位时间内从行波泵内流出的磁性流体的体积由1.9 ml增加到3.1 ml；随着磁场强度的不断增加，磁性流体流量的变化率由于磁场对其粘度的影响而减小；而磁性流体的饱和磁化强度越大，其流量也越大。

The rules of fluid rate with different technical parameters: the increase of electromagnetic force causes the increases of the fluid rates at S/L interface and free surface, the decrease of skin depth, the increase of electric current density which will make the fluid at free surface flowing faster, while it doesnt affect the fluid rate at S/L interface. When the height of melt increases, the both of fluid rates will increase too. The increase of the width-thickness ratio augments the fluid rates along the wider edges at S/L interface evidently, while the rates along the narrow edges will have little change, and the rate at free surface has little change too. The increase of overheat degree minishes the range of mush zone, while the fluid rates at S/L interface and free surface will increase evidently.

流速的大小随各种不同工艺因素的变化呈现出一定的变化规律：随电磁力的增大，固液界面以及自由表面处的流速都会增大；集肤层渗入深度变薄，电流密度增大，会导致自由表面上流动的加强，但对固液界面处的流动速度影响不大；熔区高度的增加，也会使固液界面及自由表面处的流动增强；宽厚比增大时，固液界面上沿宽面方向的流动显著增强，但窄面方向流速变化不大，同时自由表面上流速变化也较小；过热度及温度梯度的增大，使糊状区减小，导致固液界面及自由表面处的流速显著增大。
