Welcome at the website of the CP4GE research group

The Computational Physics 4 Green Energy (CP4GE) group of Prof. Dr. Lohbreier offers multiphysical simulations to support partners in industry and academia during the development or improvement process of green technologies. To acquire a better understanding, computer simulations provide many advantages and unique possibilities compared to experimental methods.

The world around us is determined by the laws of physics which are typically described by partial differential equations (PDEs). However, current problems in academia and industry are often too complex to be solved analytically. Numerical simulations are the method of choice: the questions are formulated as a numerical model and the PDEs can be

solved approximately. A well-established numerical technique to solve these equations is the Finite Element Method (FEM). Additionally, in many applications, considering only one physical aspect is not enough. More equations - corresponding to two or more physical regimes - need to be solved in a coupled manner. This is what makes up "multiphysical simulation" and defines our area of expertise. Besides the simulative expertise, each group member is an experienced experimental physicist. The team is always interested in conducting accompanying experiments in the laboratories at the Nuremberg Institute of Technology or at the R&D laboratories of the project partner. This combination of simulative and experimental expertise is beneficial for the validation of the simulation model.

Ongoing third-party funded projects

E|MPOWER - Automated Manufacturing Processes for Electric Road Systems for the Electrification of Heavy-Goods Transport

In E|MPOWER (Effiziente Modularisierung induktiver Leistungsübertrager im Schwerlastverkehrt), automated production and deployment techniques for an Electric Road System (ERS) are investigated. The goal is the realization of a 1 km dynamic wirless power transfer section on a public Autobahn. The consortium consists of partners from industry, academia and the german state.

Together with the Institute ELSYS, the research group investigates a loss modell for the ERS. The collaborative project is founded by the Federal Ministry for Economic Affairs and Climate Action (BMWK).

Further research activites

Proton Exchange Membrane Fuel Cell (PEMFC)

The research group is an associated partner in the Institute for Applied Hydrogen Research, Electro- and Thermochemical Energy Systems (H2Ohm). Reserachers across the THN are members in this joint reserach facility. The complexitiy of the PEMFC makes a multiphysical simulation approach necessary to investigate this technology. 

Energy Harvesting

Several effects are suitable to harvest ambient energy to supply low-power electronical devices (e.g. sensors). In cooperation with the Fraunhofer IIS, we investigate the potential of harvester based technologies in several application fields.

Printing of organic photovoltaics

In cooperation with the Solar Factory of the Future (Solarfabrik der Zukunft), the coating process of functional layers in the context of organic photovoltaics is investigated.

Since many years, computer simulations have been established as a “third pillar” in R&D. If you are involved in a R&D process and problems encountered which you cannot solve satisfactorily with your methods, multiphysical simulations might be benefical for you. Because numerical simulations allow a deep insight, our methods can contribute to a better understanding of your process.The group is constantly interested in new projects.
