Göteborg Ansök senast: 30 november

Do you want to have fun at work?

With us, we have fun and develop all the time. We continuously run larger and smaller customer projects and assignments at our office in Lindholmen, where we jointly help our customers take their product to the next level. Two examples of our projects:

FSI analyses of air intake

Semcon contributed with expertise in simulation to ensure function and that requirements were met for a new type of large-scale industrial air intake. Several analyses were carried out, both FEA, CFD and coupled Fluid Structure (FSI) analyses.

Development of electrolyser

Development of new technology for electrolysers to be use in green hydrogen production. The project is conducted as a research and development project where Semcon contributes with a multi-disciplinary development team. The Simulation team support the project with structure and flow simulations to fulfil requirements for function, safety and efficiency of the hydrolyser.

About us

To be able to carry out these projects we need skilled simulation (CAE) engineers in both the structure and flow simulation (FEM/CFD) area.

At Semcon's Simulation department, our teams help our customers take their products to the next level. We are a mix of experienced and young hungry consultants where we learn from each other to jointly deliver the best solutions for our customers but also to develop as individuals. We are allowed to have different views and perspectives on things, but we value the same things; balance in life, having fun together and getting things done.

Master thesis Fluid Mechanics (CFD)

Right now, we are looking for Master of Science students who wants to perform their Master thesis with us. Within the fluid mechanics area, we have the following Master thesis suggestions.

Master thesis 1:

Title:

Simulation of mixer and tank cleaning process – collaboration with Metenova

Description:
In the life-science industry, mixers and tanks need to be cleaned and sterilized before they can be used again. A cleaning nozzle is inserted into the empty tank with the mixers in place, in order to spray the equipment with high-pressure water jets. Since the inside of the tank and the geometry of the mixer can be complex, it is not an easy task to find the optimal position for the cleaning nozzle. Traditionally, the cleaning nozzle position has been determined through laborious manual tests on prototypes.

The process of finding the optimal cleaning nozzle position can also be performed on a virtual prototype with the help of Computational Fluid Dynamics simulations. This will reduce or eliminate the need for costly and time-consuming manual prototype tests.

In this project, a simulation method should be developed for the purpose of identifying the optimal cleaning nozzle position. The simulations are to be compared with and validated against physical tests to be performed at the Metenova facilities.

Master thesis 2:

Title:
Meshless simulation of the flow in a decanter centrifuge

Description:
Decanter centrifuges are used to separate solid materials from liquids in a slurry. Common applications are for example waste-water treatment plants as well as the pulp and paper and food processing industries. The process enables reduced emissions of environmentally polluted particles as well as reduced transport of slurry.

In a previous thesis project, a finite-volume based simulation method has been developed. The aim of this thesis project is to establish a meshless simulation method for analysis of the decanter centrifuge and thereby provide insight into the process inside of the centrifuge. The information gained can be used to increase efficiency, to enable optimization of mechanical parts as well as the associated control systems to solve existing problem modes.

Master thesis 3:

Title:
Simulation of particles in suspension

Description:
When mixing particle suspensions, it is important to verify a good mixture. The particles may have a different density than the liquid and it is then important to prevent the particles from accumulation, for example, at the bottom – a phenomenon called sedimentation. Many times, this needs to be done while not exceeding a certain threshold for shear stress. Typical examples of particles in suspension are found in, amongst others, the life-science, food- and process industries. Virtual models using Computational Fluid Dynamics simulation can be used to analyze the mixing process and the sedimentation behavior.

The project aims at developing a computationally efficient method for simulating mixing of particles into liquids. Both finite volume and meshless CFD methods will be used and compared in terms of numerical accuracy and efficiency.
