Job Description

Industrial Dip-Coating Process Study

We are seeking a highly motivated PhD candidate to join our research team at the Center for Material Forming (Cemef) of Ecole des Mines de Paris – PSL University. The successful candidate will work on a PhD thesis project focused on the study of industrial dip-coating processes using complex shapes and non-Newtonian fluids.

Project Overview

The project aims to understand, predict, and tune final deposited thicknesses on arbitrarily complex geometries, playing on bath rheology and object removal trajectories and speeds. The candidate will use an experimental and theoretical approach to apprehend all unitary mechanisms and instabilities at play when an object is covered by yield stress fluids (the bath), and when it is simply immersed and removed from it by translation movement, with model geometries (spheres, plaques...).

Research Objectives

The main goal of this PhD thesis is to develop a comprehensive understanding of the dip-coating process and to design a numerical simulation code to predict and optimize the final deposited thicknesses. The candidate will work on the following objectives:

  • Experimental device development: design and build a laboratory-scale robot arm to perform complex bath removal moves.
  • Layer thickness measurements: use local laser distance sensors and on-board cameras to measure layer thicknesses and characterize dripping and flow.
  • Layers flow modeling: implement a numerical simulation code to model the flow of non-Newtonian fluids and predict final deposited thicknesses.

Working Conditions

The PhD thesis will take place in the Center for Material Forming (Cemef) of Ecole des Mines de Paris – PSL University, located on Pierre Laffitte Campus in Sophia Antipolis (France). The candidate will be part of the Cemef Computing and Fluids research team and will have the opportunity to interact with Stellantis, the project industrial partner.

Requirements

We are looking for a highly motivated and talented candidate with a strong background in fluid dynamics, coating processes, and numerical simulations. The candidate should have excellent communication and teamwork skills and be able to work independently.

How to Apply

Interested candidates should send their application, including a CV, a cover letter, and contact information for at least two references, to the contact person listed below.
