Johan Padding

Open PhD position at the group of Professor Johan Padding at the Delft University of Technology (Faculty of Mechanical Engineering, Process & Energy Department). This doctoral project focuses on CFD-FEM modelling of electrically heated reactor concepts with and without reactions, with a strong emphasis on CO2 conversion and the design of reactors for a more sustainable chemical industry. The research combines electromagnetics, thermo-hydraulics, and reaction engineering to develop innovative heating concepts, including resistive heating, impedance heating, and induction heating. The position is especially relevant for candidates interested in chemical engineering, electrical engineering, applied physics, multiphysics simulation, and sustainable engineering. The post explicitly asks for an MSc degree in Electrical Engineering, Chemical Engineering, Applied Physics, or a related field, plus experience with FEM/FVM modelling and multiphysics simulations. The work will be carried out in collaboration with researchers and industry partners from Delft University of Technology, Eindhoven University of Technology, and beyond, aiming to accelerate the transition from fossil-based processes toward greener, electrically powered reactor technologies. Application deadline: 10 July 2026. Interested candidates should apply via the TU Delft careers portal using the provided job link.

This PhD position at Delft University of Technology focuses on the development and modelling of electrically heated reactor concepts for CO2 conversion, aiming to advance sustainable chemical processes. The project addresses the challenge of heating and heat management in CO2 conversion reactors, particularly for high-temperature endothermic reactions such as dry reforming of biomethane. The research will explore electric heating technologies powered by green electricity, facilitating the transition from conventional fossil-fuel heated refining processes to future-oriented, carbon-based chemistry. As a doctoral candidate, you will integrate knowledge from electromagnetism, thermo-hydraulics, and reaction kinetics to develop both surface heating (resistive and impedance heating) and volume heating (impedance and induction heating) solutions for catalytic flow reactors. The work is conducted within the Process and Energy Department of the Mechanical Engineering Faculty, in collaboration with the Electrical Engineering Faculty at TU Delft and the Chemical Engineering and Chemistry Department at TU Eindhoven. You will design, model, and evaluate resistive heating concepts, perform theory reviews, and develop guidelines for reactor design considering electrical breakdown strength. Advanced internal resistive heating technologies will be tested using CFD-FEM models and demonstrated experimentally for dry methane reforming. For volume heating, the project involves designing integrated 3D-printed structures that combine heating functionality with active catalyst materials. You will also develop and assess impedance and inductive heating concepts, including direct inductive heating and auto-inductive effects in various reactor geometries. These configurations will be evaluated and tested at TU Eindhoven to identify optimal operation modes and demonstrate their effectiveness for CO2 conversion reactions. The position offers a 4-year employment contract, with an initial 1.5-year contract and a progress assessment, followed by a 2.5-year extension upon satisfactory performance. Salary ranges from €3059 to €3881 gross per month, with additional benefits such as holiday allowance, end-of-year bonus, health insurance discounts, and flexible work schedules. As a PhD candidate, you will be enrolled in the TU Delft Graduate School, benefiting from a supportive research environment, academic staff, and a mentor. The university provides resources for relocation and integration into the Netherlands, including support for accompanying partners. Applicants must hold an MSc in Electrical Engineering, Chemical Engineering, Applied Physics, or a related field, with proven experience in finite element and/or finite volume modelling in a multi-physics context. Affinity with chemical reactor engineering and strong knowledge of Maxwell's equations are required. English proficiency suitable for doctoral education and scientific writing is essential. The ideal candidate is a pioneering, communicative team player, comfortable in a multidisciplinary environment. To apply, submit your CV, cover letter, and a detailed list of marks for your BSc/MSc courses online by 10 July 2026. Address your application to Prof. dr. ir. Johan Padding. Applications via email or post will not be processed. For further information, refer to the Graduate Schools Admission Requirements and the university's knowledge security policy.
