Opening of new physical modelling space
On 27 March, a new physical modelling space was opened to support validation of computational fluid dynamics simulations. The space provides a controlled environment for systematic investigation of single- and multiphase flow phenomena.
Facility features:
- Two 1:5 scale physical models of AOD converters, equipped with tuyere-specific rotameters for gas flow control. One model is a vessel-in-box configuration for fluid mechanical measurements, while the other includes a dedicated support structure.
- A 1:5 scale ladle model (vessel-in-box) with gas flow control via either a mass flow controller or a rotameter.
- A box model for detailed study of gas injection with a single tuyere, with gas flow control via either a mass flow controller or a rotameter.
Measurement capabilities:
- Particle Image Velocimetry (PIV)
- High-speed imaging
- Configurable camera mountings (top, side, and bottom views)
- Tracer-based mixing time measurements
- Vibration and torque measurements
The launch brought together around 25 visitors from both the University of Oulu and industry. Cakes from a local bakery were served alongside coffee and refreshments. The inaugural gas injection was initiated by Senior R&D Engineer Outi Mure from Outokumpu, who opened the gas valve.
