In our previous study (Part 1); by using the graphic of Bergeron, we have drawn the relationships which allow calculating flows and pressures at the valve and the reservoir, considering that pressure losses are negligible. Now, we assume in this second co... see more

We develop, in this paper, a method of calculating the water hammer inspired by the graphic construction of Bergeron, which we qualify as analytical method. In helping us of these graphs, we get the relationships that allow calculating the flow rates... see more

Pressure Relief Valves (PRVs) are key elements of any hydraulic system in the process industry, especially in chemical plants or hydraulic power transmission systems. Their task is to maintain the system pressure beneath a prescribed maximum pressure and ... see more

The protective structures required for performing critical operations are vulnerable to the blast and shock loads of advanced weapons. A blast valve is an important component of such structures for ventilation during normal conditions and for protection f... see more

Reed valve is a key component of reciprocating compressors affecting the efficiency and reliability of the refrigeration system. In order to further investigate the influence of structural parameters on reed valve motion characteristics, theoretical and e... see more

In this paper we present various pneumatically actuated microfluidic valves to enable user-defined fluid management within a microfluidic chip. To identify a feasible valve design, certain valve concepts are simulated in ANSYS to investigate the pressure ... see more

Background: Tricuspid valve detachment (TVD) may improve the access for closing certain ventricular septal defects (VSDs), but it has some potential risks. We aimed to study the benefits and drawbacks of this technique.Methods: The midterm outcomes of all... see more
