Abstract

Centrifugal casting offers one route through to high quality products in difficult to cast high temperature low superheat alloys. The coupling of free surface flows and complex rotating geometries, resulting in significant centrifugal forces, combined with rapid heat transfer and solidification yields a significant computational modelling challenge. The objective of the work reported here is to develop a comprehensive computational model of centrifugal casting that can reliably predict the macro-defects that arise from the process. In this contribution we describe: • A computational framework for modelling the filling and solidification of centrifugal castings, • a series of large scale centrifugal casting experiments with the full complexity of a target industrial system, together with • a sensitivity study of a principal boundary conditions.
