Phd Rheological Behaviour of 3D Printed Energetic Materials

Delft University of Technology has an opening PhD position in mechanical engineering. Applications will be evaluated immediately.

The 3mE Faculty trains committed engineering students, PhD candidates and post-doctoral researchers in groundbreaking scientific research in the fields of mechanical, maritime and materials engineering. 3mE is the epitome of a dynamic, innovative faculty, with a European scope that contributes demonstrable economic and social benefits.

The Department of Process and Energy (P&E) focuses on process and energy technology in a mechanical engineering context, meaning that a process or energy conversion is part of an apparatus. We envision that in the coming decades a transition from fossil/conventional energy conversion towards full electrification will take place in society. Our objective is to develop processes supporting this transition by making existing processes more efficient and developing novel green technologies that use electricity as a primary energy source to produce heavy transportation fuels and bulk chemicals. Continuum fluids are the common denominator, either as a process material, carrier, or solvent, or as a medium through which a transport, separation, or chemical process is carried out.

The vacant position is in the sections Multiphase Systems (MPS) and Intensified Reaction and Separation Systems (IRS). The MPS section studies fundamental and applied aspects of multiphase flows, inspired by industrial applications. Research is done using state-of-the-art numerical tools (DNS, immersed boundary methods) and experimental techniques. The IRS section advances novel, sustainable solutions by bridging process technology research to other scientific disciplines like material sciences, physical chemistry, catalysis and physics.

Energetic formulations are heterogeneous systems, consisting of solid particles (usually the energetic material, EM) embedded in a polymer-based matrix. Traditionally, these formulations are processed using pressing, mixing/casting, and extrusion. With the advent of additive manufacturing (3D-printing), great benefits are foreseen when applying the design freedom of additive manufacturing to energetic materials. Within this PhD project, the candidate will further extend the current understanding of additive manufacturing of energetic materials as a new and innovative processing tool. The aim of the proposed PhD project is to understand and numerically model additive manufacturing of heterogeneous, two-phase flows consisting of solid particles (energetic materials) dispersed in a liquid medium. This aim is to be achieved by carrying out experiments using additive manufacturing techniques complemented with modifying or developing numerical models with which the experimental results can be described and understood. The results are foreseen to be published in scientific journals or presented at conferences. The project will be performed in close collaboration with TNO.

Applicants should have an MSc degree in Mechanical Engineering, Chemical Engineering, Applied Physics or a related field. Background knowledge of multiphase flow of heterogeneous mixtures will be an advantage. The applicant is expected to have an affinity with both experimental and numerical work. For this PhD position, a security screening by the General Intelligence and Security Service (AIVD) will be performed. This screening requires the candidate to have nationality in a NATO country.

The TU Delft offers a customisable compensation package, a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children's Centre offers childcare and an international primary school. Dual Career Services offers support to accompanying partners. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.

As a PhD candidate you will be enrolled in the TU Delft Graduate School. The TU Delft Graduate School provides an inspiring research environment; an excellent team of supervisors, academic staff and a mentor; and a Doctoral Education Programme aimed at developing your transferable, discipline-related and research skills.
