Fatigue Analysis Using Parametric Modeling For Agitator Nozzle

Abstract

Stress vessels usually encompass outside attachments and require openings. The most typically used external attachments are nozzles with joints. Pressure concentrations arise in joints under diverse loading situations. Similarly, geometric discontinuities and welding issues, in addition to flaws, make joints the weakest factor and the source of failure for the entire shape. Aside from that, if an outside element consisting of an agitator is hooked up to the vessel, it is also at risk of fatigue failure. So, the layout of a vessel based totally on the ASME strain vessel layout code is simply necessary. This thesis outlines the Plan of Ellipsoidal head of weight vessel with fomenter spout connected to it for certain stacking condition. Plan calculations of Spout made in ellipsoidal head are as per ASME weight vessel plan code SEC VIII DIV I. A 3D version of the vessel socket connection was created in ANSYS Workbench. For a nozzle with an agitator in a 2:1 ellipsoidal head with an inner diameter of 4500 mm, a structural evaluation below the inner stress load and outside load is accomplished, and the same existence is calculated. The effects show that the layout passes the given load conditions and that further upgrades are possible. Therefore, optimizing the layout of the 1011 lifecycle is done through evaluation.
