**Job description**:
**Project description**

The production of metal powders for PM and AM requires high sphericity, uniform particle distribution, and optimal size characteristics. Molten metal atomization is the key process that transforms molten material into fine, spherical particles using high-velocity gas streams. This project aims to develop an **experimentally validated CFD model** for this process, advancing the understanding of the **physical and chemical mechanisms** involved in **close-coupled gas atomization (CCGA).The overall objective of this study is the development of the experimentally validated CFD model for molten metal atomization. **To pursue the overall objective, in this project we aim to:

- **_Goal 1_**_ _**_Develop a gas atomization CFD model_***

At TU/e, a numerical framework describing the molten metal droplet behavior during gas atomization is under development. This model is crucial as it provides a theoretical basis for understanding and predicting the behavior of molten metal during atomization. The model must include: (i) primary breakup, (ii) secondary breakup, (iii) coupling between primary and secondary breakups.
- **_Goal 2 Perform digital inline holography (DIH) experiments_**

To validate and refine our CFD model, we need experimental data of spray and droplet characteristics. At Technion, digital inline holography experiments on close-coupled gas atomization (CCGA) have been performed using water and air. The setup and experimental technique will be used to carry out atomization experiments of glycerol/water mixtures (change in viscosity) and solutions with surfactants (change in surface tension). These liquids with different physical properties are used to mimic the typical properties of molten metal. The experiments will provide critical data on velocity and droplet size distributions, as well as the number of droplets per unit volume and their spatial distribution in the spray.
- **_Goal 3 Validate the gas atomization model with experimental results_**

Validation is essential to ensure the CFD model's accuracy and reliability. The gas atomization CFD model developed at TU/e will be validated using the experimental results obtained from DIH at Technion. This validation will confirm the model's ability to accurately simulate the atomization process.

**Key Responsibilities**:

- **Develop a CFD model for gas atomization**: Work on a numerical framework that simulates molten metal breakup during atomization, covering primary and secondary breakup processes.
- **Conduct digital inline holography (DIH) experiments**: Design and perform experiments using surrogate liquids to capture critical data on spray dynamics, droplet sizes, and velocities.
- **Validate the CFD model**: Use experimental results to validate and refine the CFD model, ensuring its accuracy in predicting the atomization process.
- **Collaborate with Technion
- Israel Institute of Technology**: Participate in cross-institutional research, utilizing both experimental and computational techniques to enhance the project’s outcomes.

**Why Join Us?**

This PhD position offers a unique opportunity to work on cutting-edge research that impacts industries such as additive manufacturing, steelmaking, and energy storage. You will gain access to state-of-the-art experimental and computational facilities and contribute to sustainable, innovative manufacturing technologies.

If you are an enthusiastic researcher with a passion for fluid dynamics and atomization processes, we encourage you to apply.

**Project team**

You will work with a dynamic team of experts, including Dr. Giulia Finotello and Prof. Niels Deen at TU/e, and Prof. René van Hout at Technion. The research interests of Giulia Finotello include development of advanced experimental techniques and numerical tools to investigate spraying dynamics. Prof. René van Hout is an expert in multiphase flow and particle behavior in turbulent flows. He specializes in advanced experimental techniques such as Particle Image Velocimetry and digital holography. This collaboration will enable the development of a robust, experimentally validated multiphase and multi-scale CFD model for molten metal atomization.

As part of the EuroTech PhD program you will collaborate with Technion - Israel Institute of Technology in the group of prof. van Hout. Due to the situation in the region, a stay in Technion is not compulsory, and the possibility to perform it (6 to 12 months) will be evaluated in the future. This project is also supported by the Eindhoven Institute for Renewable Energy Systems EIRES, and you will become an active member of the EIRES community

**Job requirements**:

- Strong background in fluid dynamics, heat transfer, and computational modeling (CFD) with a proven particle/flow simulation experience in multiphase flows
- Experience with Open Foam is beneficial
- Experience with experimental techniques such as digital holography and/or PIV is beneficia
