POSTDOC Position in Thermal Topology Optimization for Mold Cooling - H/F

Job description:

During forming processes such as injection molding, the cooling stage is of primary interest. It plays a crucial role in the productivity of the process and the quality of the manufactured products. Therefore, great attention is placed on the design of an effective cooling system. During previous projects, IPC has developed a strong experience in the design and optimization of the cooling system in a mold. One of the main results is a patent named MCOOL®, which allows to extract the thermal print of the mold, i.e. the future optimal cooling system.
Assistant Professor Joe Alexandersen, University of Southern Denmark, has a strong background and competencies in thermal topology optimization. One example is the design of passive coolers for light-emitting diode lamps using topology optimization. The designs are optimized for natural convection and the passive cooling it provides the optimized structure.
The present project will apply topology optimization for fluid flow and heat transfer in the laminar and turbulent regime to improve the cooling of a plastic part during the injection process.

The main objective of the project is to develop and adapt topology optimization to determine the optimal fluid flow paths of conformal cooling systems, that minimizes the pressure drop and maximizes the heat exchange. The goal will be to include various manufacturing and performance constraints.
Secondly, the project seeks to develop a methodology that can be integrated into COMSOL Multiphysics for applications. This requires exploration of efficient and potentially simplified models for including turbulent effects.

Kind of job:

1. Literature survey on topology optimization for heat transfer, turbulent flow, and cooling system design
2. CFD and heat transfer simulations in COMSOL
3. Develop topology optimization method for integration into COMSOL
4. Explore methods for taking turbulence into account through full or simplified models
5. Evaluate the efficiency of the proposed methodology


The successful candidate should have a Ph.D. degree in numerical mechanical engineering, science or applied mathematics. Strong knowledge in optimization methods, numerical methods, programming (Matlab, python, C++). The knowledge of COMSOL Multiphysics is a plus. The candidate must be dynamic and rigorous, with an ability to work in an international multidisciplinary environment. A collaborative mindset and proven track record is an advantage. Excellent communication skills and interpersonal skills, as well as an excellent command of the English language (both written and spoken) are desired.


Employment as a postdoc is temporary and will cease without further notice at the end of the period of 12 months. The successful applicant will be employed in accordance with the agreement between IPC.
Employment as a postdoc requires scientific qualifications at PhD level.
The position will start as soon as possible, preferably 1st of June 2022 at the latest.
Research will be predominant in the position.

1st of June 2022
