Limit Pressure for a Protruding Cylindrical Nozzle in a Spherical Pressure Vessel

Abstract

Using the one-moment limited interaction surface, an exact solution verified by obtaining coincident upper and lower bounds has been calculated for the limit pressure for a protruding cylindrical nozzle in a spherical pressure vessel. Using a particular mechanism configuration involving the sphere and the external part of the branch which covers a wide range of the parameters r/R, R/T and t/T, a comprehensive study of the effect of the internal protrusion has been made. Results of the limit pressure for a wide range of parameters are presented.
