Pressure control valve (PCV) is implemented in internal combustion engine to regulate crankcase pressure. In this study, the performance of a diaphragm PCV valve is investigated numerically and experimentally. Firstly, numerical simulation is carried out using commercial code to predict the flow and pressure distribution inside the valve. Furthermore, downstream and upstream pressure of the val...
According to medical studies, cardiovascular diseases are the most common and most important risk factor for mortality and disability in Iran. Hence, the National Blood Pressure Control Program was implemented throughout the country from May 17, 2018 (coinciding with the World Blood Pressure Control Day) to July 6th. One of the important issues in blood pressure screening is the correct diagnos...
When a natural gas pipeline ruptures, the adjacent upstream and downstream automatic control valves (ACV) should close quickly to prevent leakage or explosion. The differential pressure set point (DPS) at each valve location is the main criteria for value setting in ACV actions. If the DPS is not properly adjusted, the ACV may mistakenly close or it may not take any actions at a proper ti...
