Application of Pipe Network Hydraulic Calculation Theory in Mine Well Water Supply System Improvement
Coal mine safety rules show: we must establish and improve dustproof and water supply system in the mine well.Based on the comprehensive study and analysis on the status of water supply system in Tangshan Mining Company Tieyi District and the reconstruction plan of water supply system,this paper used the pipe network hydraulic calculation theory to calculate the existing and new water supply system to build and improve the dustproof and water supply system and ensure safety of mine.
This work describes a high order accurate discontinuous finite element method for the numerical solution of the equations governing compressible inviscid flows. Our investigation has focused on the problem of correctly prescribing the boundary conditions along curved boundaries. “Ale show by numerical testing that, in the presence of curved boundaries, a high order approximation of the solution requires a corresponding high-order approximation of the geometry of the domain. Numerical solutions of transonic flows are presented which illustrate the versatility and the accuracy of the proposed method.
