A lightweight three-phase Fluid Catalytic Cracking riser model for real-time simulation and interactive three-dimensional visualization

摘要: In this paper, a lightweight physical model and fast numerical solver are proposed for the rendering of fluid catalytic cracking (FCC) dynamics in riser cylinder reactor part FCC unit. For Real Time requirements, trade-off between fidelity complexity is needed. The choice way to solve it numerically here completely driven by virtual reality requirements on standard Personal Computer. It has been possible design real time able show three-phase flow depending parameters (number oil injection inlets, angles, rates, temperature cracking). obtained qualitatively agreement with what expected such kind reactive flows: expansion zones, recirculating zones catalyst, turbulence, privileged paths gas phase, etc. Of course, purely qualitative, but accurate enough reproduce emerging behaviors roughly understand happens reactor. This course important from Engineering point view. A Graphic User Interface (GUI) allows near-Real (RT) user interaction environmental instantaneous response flow. VTK-based visualization module us visualize three-dimensional fields three phases, simultaneously or independently. software was built open source technologies including Python, VTK, SWIG C++ wrapping wxPython portable over different operating systems like MS Windows Linux. We think that work new milestone toward whole unit closed-loop control simulator context training engineering. perspective use Teraflop-enabled Double Precision multicore GPU co-processors next months should allow much more computational cells particles, maybe up speedup factor about 100 convincing realistic rendering. Moreover, ability hardware create binding data arrays objects high rate frames per second an attractive feature visualization, simulation interaction.
