Journal paper on the thermodynamics of Fe–B–V systems

APRIL 23, 2019
A paper entitled "Thermodynamic Description of Ternary Fe-B-X Systems. Part 4: Fe-B-V" was published in Archives of Metallurgy and Materials. This paper represents a fourth part of a series of papers focussing on the thermodynamic description of Fe–B–X systems for modeling solidification of steels.

Journal paper on numerical modelling of a physical model of a steelmaking ladle

FEBRUARY 10, 2019
A paper entitled "Modelling of the Effect of the Gas Flow Rate on the Fluid Flow and Open-Eye Formation in a Water Model of a Steelmaking Ladle" was published recently Steel Research International. In this paper, a 1:5 scale physical model of a 150 t ladle was set up to study the effect of gas flow rate on the open eye formation. The physical model was then simulated with an Eulerian VOF model. The simulation results were found to be in good agreement with the measured ones.

Research visit to RWTH Aachen University begins

JANUARY 31, 2019
To advance our on-going research on hot metal desulphurisation, I am working temporarily as a visiting researcher at RWTH Aachen until Autumn 2019. The work in Aachen focuses on physical modelling of reagent injection in hot metal desulphurisation. With its approximately 45000 students and 550 professors, RWTH Aachen University is as the largest technical university in Germany.



Appointment to vice-chairman of the Research Community for Steel Production, Fabrication and Applications

JANUARY 25, 2019
Succeeding Dr. Olli Nousiainen, I was appointed to vice-chairman of the Research Community for Steel Production, Fabrication and Applications, a cross-discipline organisation covering all steel research at University of Oulu. In this task I will support the new chairman Prof. Jari Larkiola.

Research visit to Northeastern University in Shenyang, China

JANUARY 15, 2019
In continuation of our recent collaboration, I visited the Institute of Metallurgy Multiphase Transfer and Reaction Engineering at Northeastern University in Shenyang, China, where Mr. Eshwar Ramasetti is conducting computational fluid dynamics modelling on open eye formation and mixing of alloying elements in ladle treatments. I serve as one of the instructors of his doctoral thesis work at University of Oulu.
