Abstract

Abstract: The Kriging response surface of single parameter and double parameters versus mass loss of valve spool about bonnet length, bonnet external radius and chamber inner radius of a new type throttle valve used in Managed Pressure Drilling was carried out by using CFX and ANSYS-Design Exploration. The results show that these dimensions have significant influence on erosion mass loss of valve spool. In order to improve the anti-erosion ability of the spool and enhance the service life of the whole valve, the multi-objective genetic algorithm was used for dimensional optimization design of the mentioned variables. After optimization design, the averaged erosion mass loss of plug was decreased 30.2% than that in original chamber dimensions. The detail analysis of spool contour in symmetry plane indicates the erosion rate of majority points on the contour are decreased obviously, and especially significant at the back side of the spool.
