Job Description
Spray quenching is a key process in cooling applications and SCR exhaust aftertreatment systems. To improve our understanding of the underlying physics, a numerical 3D CFD model of a spray quenching test bench will be developed using AVL Fire M. 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
* Compare and discuss results with physical expectations and experimental data
Profile Description
* Master's student in Mechanical Engineering, Process Engineering, Chemical Engineering, Energy Technology or a related field
* Background in fluid mechanics, heat and mass transfer
* Basic knowledge of CFD; prior experience with AVL Fire M or comparable software is an advantage
* Independent, structured and analytical working style
We Offer
* You can write your thesis independently and receive professional guidance and support from our experienced employees.
* You will have the opportunity to exchange ideas with experts in the company and benefit from their expertise.
* Take the opportunity to immerse yourself in the world of AVL and embed your theoretical knowledge in a practical environment.
