Turbodrill is a type of hydraulic axial turbomachinery which has a multistage blade consisting of stators and rotors. In this paper, a turbodrill blade that can be applied in crystallized section under high temperature and pressure conditions is developed. On the basis of Euler equations, the law of energy transfer is analyzed and the output characteristics of turbodrill blade are proposed. Moreover, considering the properties of the layer and the bole-hole conditions, the radical size, the geometrical dimension, and the blade profile are optimized. A computational model of a single-stage blade is built on theANSYS CFDinto which the three-dimensional model of turbodrill is input. In light of the distribution law of the pressure and flow field, the functions of the turbodrill blade are improved and optimized. The turbodrill blade optimization model was verified based on laboratory experiments. The results show that the design meets the deep hard rock mineral exploration application and provides good references for further study.

Enormous amounts of wastes have been produced due to extensive use of carbon fiber/epoxy resin (CF/EP) composites. The fact that the supercritical fluid can be used to recycle these composites efficiently has attracted widespread concerns. A three-dimensional model of CF/EP laminates considering the interfacial layers was established. The internal stress distribution of laminates was simulated based on a heat transfer model; and the change of shear stress with supercritical temperature and pressure was investigated. The results show that the shear stress concentration was located in the interfacial layers; the maximum shear stress can be expressed by a curve of convex parabola to the temperature; and the most serious damage occurred in interfacial layers when temperature approached the glass-transition temperature of resin.

Based on the 3DMine three-dimensional mining software, a geological database model of the Changpai area is established, and a three-dimensional model of the ore body is established based on the principle and geological understanding of the circle. We carried out sample combination by a geological database model to process ore bodies of erratic high grades. We also stablished a block model, and used single assignment and ordinary Kriging method to assign value to the block model, used attribute visualization to intuitively reflect the distribution law of the ore grade in a three-dimensional space, and the block report can quickly estimate the grade, volume, ore quantity, etc., of which the results are more accurate. The common Kriging method has obvious advantages in valuation, and it is worthy for further promotion in the estimation of uranium reserves.

The solidification process, the formation mechanism and distribution law of microporosity of the ball milling machine head cover made by SVEDALA corporation of USA were simulated by computer. The Solidworks software was used to generate three-dimensional model of cast parts and the Hua-casting software was employed to simulate the casting process. The simulated results show that significant microporosity was found in the middle of two casting heads and at the place of gudgeon journal because of insufficient chilling degree. The processing rationality was judged through the computer-aided technology, by which some drawbacks of the traditional process were overcome and the process design quality was improved.

Dust Distribution

In order to study urban surface dust distribution, a three-dimensional model is proposed and the distribution of wind and the distribution law of air pollutants are researched. 3D campus of Shanghai University as a typical area is selected. The standard height (Twenty two meters) of teaching building for reference has been chosen. In different distances such as Eight、Twelve、Fifteen、Twenty meters, the amount and distribution of wind speed were obtained from simulation using FLUENT software. Combined with the particulate of air pollution’s distribution in urban surface, the optimized design of the main campus’s building spacing is analyzed. The results show that when the building space is about Fifteen meters, the concentration of pollutants and the distribution of wind speed is optimized.

Airborne Magnetic

The airborne magnetic method is one of the most significantly applied approaches in mineral exploration. This magnetic method has been widely used in recent years due to its extensive coverage, lower cost than other methods and coverage of impassable areas and forests. For many years in Iran, the magnetic method has been utilized by authorities to survey ore deposits and to prepare structural and geological maps. This paper presents part of the Dehshir area exploration data of airborne surveys by helicopter with flight line spacing of 250 meters and flight height of 40 meters conducted by Geological Survey and Mineral Exploration of Iran. Furthermore, among the potential areas in the Dehshir area is the studied hereby area of Block C2 of Sourk mine. This region in Yazd province with a 4.1 km2 area is located at 95 km northwest of Yazd city. The purpose of this paper is to present a three-dimensional model of magnetic data and its validation using drilling data. The three-dimensional modeling of magnetic data has been processed by Inversion method. Next, the locations of boreholes were proposed for drilling. Then, the boreholes data is used to evaluate the geophysical method model by comparing the three-dimensional modeling of magnetic data and three-dimensional modeling of the proposed drilled boreholes data.

In order to research the temperature distribution law of the interstitial oil film on the hydrostatic center rack, the interstitial oil film on the hydrostatic center rack is taken as the research subject. Firstly, a three-dimensional model of the interstitial oil film is built by UG software. Secondly, the constructed three-dimensional model is meshed by ICEM CFD software. Lastly, the constructed finite element model is simulated using the finite element analysis software ANSYS CFX. The results of the simulation show that the temperature near the oil seal edge is higher than oil chamber and oil-returning slot. If the shaft parts rotate clockwise, the temperature of the right high-temperature zone is higher than the left. The research results provide a theoretical basis for the research on the thermal distortion of the middle pillow.
