Vortrag von Prof. Pirker an der TUHH

Hiermit möchte ich Sie auf den Vortrag von Prof. Stefan Pirker vom Department of Particulate Flow Modelling der Uni Linz (Österreich) aufmerksam machen, der im Rahmen der Vortragsreihe unseres SPP 1679 am 3. April um 14:00 Uhr an meinem Institut stattfinden wird.

Das Thema lautet:

    "Can we bridge between recurrence CFD (rCFD) and process control?“

Abstract:

Recurrence CFD (rCFD) aims at an efficient representation of long-term processes (e.g. heating, chemical conversion) which slowly evolve on highly-dynamic pseudo-periodic flow fields. In such cases classical CFD simulations fail due to excess computational cost associated with the resolution of the governing flow fields.

In the framework of rCFD, short-term full CFD simulation deliver recurrence databases of the governing flow at different operating conditions. Based on statistical reasoning, rCFD then exploits these databases in order to either develop (i) generic flow fields or (ii) generic transport fields, which subsequently serve as basis for the long-term process under consideration. We further present an interpolation methodology for the representation of unsteadily varying operating conditions (i.e. between existing recurrence databases).

In applying rCFD to a set of single-phase and multiphase flows, we experienced a computational speed-up of two (flow based rCFD) to four (transport based rCFD) orders of magnitude. In many cases this dramatic speed-up allows for faster-than-realtime simulations, although we didn’t reduce the resolution of the original full CFD simulation.

Finally, we explore the possibility of incorporating such real-time rCFD simulations into process monitoring and control.
