CFD and System Simulation of Post-Combustion in Kaldo Furnace Gas Uptake

Beskrivning:

Shape the future of metallurgical process optimization with advanced simulation tools. Join us in exploring the dynamic world of Kaldo furnace operations and help develop smarter, more efficient solutions for sustainable metal refining. We are now looking for a motivated and analytical thesis student to take on a challenging project that combines system-level modeling with detailed CFD analysis. If you're passionate about combustion, fluid dynamics, and digital innovation, this is your opportunity to make a real impact. Tasks that inspire In this thesis, you will investigate the complex interactions between off-gas flow, air ingress, and heat transfer in the Kaldo furnace’s gas uptake system. Your mission is to develop a simulation workflow that combines HSC Sim and CFD to quantify post-combustion behavior and thermal loads, ultimately supporting design and operational improvements. The objective of this thesis is to develop and validate an integrated simulation methodology that combines system-level thermochemical modeling (HSC Sim) and Computational Fluid Dynamics (CFD) to analyze post-combustion phenomena in the Kaldo furnace gas uptake system. The goal is to quantify and understand how air ingress and off-gas composition influence post-combustion efficiency, gas temperature profiles, and heat transfer to the uptake hood, providing actionable insights for design optimization and operational control. Your work will include: • Estimating off-gas composition and energy balance using HSC Sim. • Building a CFD model of the gas uptake hood to simulate flow, mixing, combustion, and heat transfer. • Quantifying key performance indicators such as degree of post-combustion (CO, H₂ burnout), gas temperature distribution, and heat flux to the water-cooled hood. • Assessing how variations in air ingress and gas composition affect combustion efficiency and thermal stress. Your profile We’re looking for a master’s student in engineering, physics, or a related field with a strong interest in simulation and thermal processes. You should be familiar with CFD tools (preferably Ansys Fluent), and have a structured, analytical approach. Experience with 0d-system simulation is a plus. You communicate well in English and enjoy working both independently and collaboratively. A workplace that supports learning and innovation Whether you're working from our office in Skellefteå or remotely, you'll be part of a team that values curiosity, knowledge sharing, and real-world impact. We believe in learning by doing—and we’ll support you every step of the way. Project timeline (~6 months): • 1–2 months: Data collection and HSC modeling • 2–3 months: CFD model development and validation • 1–2 months: Parametric study, analysis, and thesis writing
