Master Thesis - 3D CFD Modeling of Spray Quenching

The work focuses on simulating the interaction between a hot gas flow and water spray injection. The study provides hands-on experience in multiphase flow simulation, droplet evaporation, spray-wall interaction, and heat transfer modeling.

• Develop a 3D model of a test bench tube with hot gas flow in AVL Fire M
• Implement and parametrize water injection using Lagrangian parcels
• Perform CFD simulations for 6 operating conditions: Low-temperature case (290ºC) with three spray dosing rates (250 g/h, 500 g/h, 2000 g/h)
• Moderate dosing case (500 g/h) with varying gas temperatures (290ºC, 350ºC, 400ºC, 450ºC)
• Analyze results regarding temperature distribution, droplet evaporation and spray–flow interaction
