Research on Three-point Centering Device of Cylindrical Drill Pipe

In the process of tightening up and screwing off the iron roughneck, it is required that the center of clamping pliers and the center of drill pipe are coincident, so as to avoid the damage of the circular guide in clamping system, and to ensure the iron roughneck work normally. While the traditional method of centering is artificial in iron roughneck, its precision is low, so it is easy to dam...

Automated Drill Design Software

This section of the report discusses a tool which can create automated 3D CAD drill models based on geometric as well as manufacturing parameters. This tool is a required component of numerical/FEmodels of FRP drilling. The tool outputs the drill in a variety of solid geometry formats which can then be meshed and used in different FE analysis packages.

Half-Pipe Anchoring: An Efficient Technique for Multiple Connection Handoff

We present half-pipe anchoring, a technique that enables multiple connection handoff mechanisms that are efficient and easy to implement. In a server cluster, these mechanisms result in better resource utilization and improved scalability. More importantly, half-pipe anchoring supports the only connection handoff mechanism that operates efficiently in heterogeneous clusters composed of speciali...

Development length of laminar magnetohydrodynamics pipe flows

In this article, a laminar magnetohydrodynamics (MHD) developing flow of an incompressible electrically conducting fluid subjected to an external magnetic field is considered. The aim of the study is to propose a correlation for computing the development length of the laminar MHD developing flow in a pipe. A numerical approach is considered to solve the problem. In the first step, the numerical...
