Abstract In empty well killing, in order to save the time and cost of killing well, dynamic replacement method is often used kill well. The main problem for wells how avoid terrible working conditions caused by flooding, such as gas carrying fluid, fluid being brought wellhead. Based on principle flooding formation basic tenets correlation experiment method, this paper incorporates viscosity, s...

a general robotic mechanism was presented for in-pipe inspection oflevel pipes with varied diameter or curved pipelines. the robot employed three legs comprised of parallelogram linkages mechanism which enables adapting to various elbow joints in the piping systems. the curvatures in pipeline are the most important constraints in front of the robot through navigation process. to study the adapt...

The direct numerical simulation (DNS) of heat transfer in a fully developed turbulent pipe flow with for various Prandtle numbers are performed to obtain statistical quantities such as turbulent heat flux, and temperature variance. Main emphasis is placed on Prandtl number effects on turbulent heat transfer in pipe flow. Probability density functions and joint probability density functions of v...

This paper discusses the development and implementation of a new ergonomic manual control system for a large construction manipulator. The manipulator consists of a 22 ton rough terrain hydraulic crane with a multifunction manipulator attachment. The combined device gives a single operator hydraulic control over eight independent joint axes allowing for dextrous positioning of large sections of...
