A comprehensive review. The kinetics of various types of chem. reactions and the influence of transport processes on the effective reaction velocity (macrokinetics) are described. A survey is given on methods to det. the kinetics of reactions. Criteria for ...
This work presents results of a comprehensive analysis of the Lenz effect due to motion of artificial heart valves during magnetic resonance imaging. The interaction of rotating metallic heart valves with magnetic fields is studied by performing a time-dom ...
In this paper, the necessity for a high pressure valve is discussed, and a design for such a valve that has been previously presented is described. This valve can be built using simple fabrication techniques available in microsystem foundries. Its fabricat ...
A dosage system for feeding a fluid (A) to a static mixer (1), said system comprising a tank (2) containing said fluid (A) at a predetermined pressure, a fluid passage (3) connecting said container (1) and tank (2), a control valve (4) provided within said ...
Industrial plants have an abundance of complex and confined areas that require systematic inspection. Maintenance work is necessary to ensure reliability and safety. In many cases, due to either size limitations or high danger, access is impossible to huma ...
Nowadays, the pump-storage power plants are a proven solution for storing electricity at large scale and offering flexibility to the power management. Therefore, the hydraulic machines are increasingly subject to off-design operation, start-up and shutdown ...
The failure of steel liner of pressure shafts of hydropower plants can have catastrophic consequences. The partial or total loss of the liner support’s rigidity is characterized by a local change of the hydro-acoustic properties and creates reflection boun ...
