In: Shape Casting: The Minerals, Metals & Materials Series, 7th International Symposium Celebrating Prof. John Campbell's 80th Birthday, pp. 53-64978-3-030-06033-6https://doi.org/10.1007/978-3-030-06034-3_5https://dspace.lib.cranfield.ac.uk/handle/1826/14394In the 1980s, John Campbell developed a new casting process from his research in the industry over a number of years. The Cosworth process was for delivering very high-quality aluminium components for the automotive industry. The process was very capital-intensive and not very flexible for smaller companies delivering lower volumes of product. However, the principles behind the process have been taken and used to develop a range of different so-called running systems to help improve the quality of castings. Some of these designs have been published in ‘Castings Handbook’ [1] authored by Campbell. This paper presents the results of an MSc project during which a number of the proposed designs from Campbell’s Mini Casting Handbook [2] for certain features in running systems have been modelled using a validated CFD software.enAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/Gravity sand castingRunning system designNumerical simulationVortex gateTrident gateBubble trapMultiple-in-gateAir entrainmentGate velocityBook chapter
