Compessible Air Flow This is a attempt to develop equations for air-distribution systems and overfall of pressure on elementary part of pneumoline. Article mcd file
Normally Closed Valve
 
This paper presents an experimental approach to investigate the influence of Normally Closed Valve's parameters on the time response in abrasive waterjet cutting. Closure speed function of actual pressure and orifice size were used. Comparison of two different polynomial models such as linear and mixed for NCV were made. Article mcd file
Double Action Hydraulic Intensifier
 
This paper represents a theoretical investigation of the mathematical model for the determination of several different parameters of the DAHI (Double Action Hydraulic Intensifier used to develop this ultra high pressure), including some parameters of the water stream and the cutting or drilling material. The semi-empirical equation for the definition of the total cycle time based on the superseding and switch time was obtained. Article mcd file
