Mathematical Modeling and Validation on a New Valve Core of the Throttle Valve in MPD

Mathematical Modeling and Validation on a New Valve Core of the Throttle Valve in MPD

To achieve different demands for pressure control in managed pressure drilling (MPD), the relationship between the pressure difference and the valve opening was analyzed in the working process of MPD throttle. The throttle flow area equation and the flow area isosurface equation at different opening...
