According to analyze the settlement characteristics of storage tank foundation at water-filling preloading stage and stable loading stage based on numerical simulation, and researching the settlement characteristics of storage tank foundation. The research results show that the deformation of storage tank foundation is “tray” in shape, and the maximum settlement appears at the place 0.65D away from the center of storage tank bottom, D is the radius of storage tank. Uplift appears at the place 1.3D away from the center of oil tank bottom, and the final uplift value is 10mm.The main factor which influences the consolidation speed of storage tank foundation is permeability coefficient.

Three basic types of similar relationship between the prototype and the model for dynamic structural model test and dynamic destructive model test were proposed in corresponding literatures. At the time the situation where various similar relationships are applicable and the technique to ensure similarity for the different goal was discussed. Here the numerical simulation of model test of water-conveyance tunnel concerning fluid-structure interaction in soft soil is studied. Based on economy and practicability of selective material for model test, the similar relationship and the technique are proposed, which are validated through the example. The results of numerical simulation show: under the specific conditions, data of the model test can completely transfer to those of the prototype by use of this type of similar skill, and get more useful information. Some new ideas are introduced to keep the similarity of the hydro-structure structures.

Main Factor

The numerical simulation method is adopted to calculate the flow field of the secondary throttle choke used in the oil field. The relationships among the flow of the secondary throttle choke, differential pressure and diameters are studied. The results of numerical simulation coincide with the experiment values, which verify that the method is correct. The results show that the flow increases with the increasing of differential pressure of the throttle choke at both ends, but the increment of the flow gradually decreases. The structure could maintain the flow not to change basically when differential pressure change in a certain scope. When the throttle diameter turns out to be small, the flow decreases, and flow-pressure curve gradually becomes aclinic. Compared with the first-class throttle diameter, the second-class throttle diameter is the main factor which effects flow changes.

Main Factor

In this paper, jetting behavior of two immiscible liquids, water as the outer liquid and silicone oil as the inner liquid in typical flow focusing microchannels were numerically studied using VOF method. At low capillary number, uniform microdroplets were obtained by the absolute instability. With the increasing of fluid flow ratio, the jet is thinner and tends to break up further away the cross junction. The results showed that the flow rate ratio is the main factor that influences the microdroplet sizes, while the frequency of microdroplets formation can be controlled mainly by the surface tension when it is in the jetting regime.
