Real-time Simulations of Metallurgical Processes
Today, digitalization with the simulation of metallurgical processes is the basis of several K1-MET projects. Metallurgical systems consist of a wide variety of time and space scales. For instance, the behaviour of the scavenging gas in a converter is unsteady and dynamic, while the chemical reactions in the converter last longer. To achieve computational fluid dynamics (CFD) for the entire process and the various scales requires considerable CPU resources. In order to resolve the long-term behaviour of dynamically recurring patterns and simulate processes with shortened computational periods, the recurrence CFD (rCFD) method is being developed. rCFD uses statistical approaches to solve the problem of the different scales by time-extrapolation of recurring flow features (see illustration), which makes it possible to describe the entire analysis period. This project explores the possibilities and limitations with the ultimate objective of producing an rCFD method that is fully developed and can be used in industry.
