Always creating more knowledge through research

XRG Simulation has made a name for itself in the field of simulation and modelling of thermal energy systems and in collaboration with renowned research institutions and companies continues to take part in challenging research projects for better energy technology. Our expertise is especially helpful for the research when it comes to complex topics. We get to the bottom of questions, learn from these and develop methods and products which further the project. Thus, we gain advanced knowledge in many areas from which our customers also benefit.

DynStart - Start-up and Transient Behaviour of Power Plants

The joined research project "DYNSTART: Start-Up and Transient Behaviour of Power Plants" will investigate the capabilities of power plants with and without CCS technologies to provide residual loads in future energy markets. The study will point out potentials and limits of operation at extra-low-load and during start-up and shut-down. Besides the process-technical aspects of the issue modern MIMO control strategies are focused in the study as can improve the power plants' abilities to fulfil future grid requirements.

The Modelica library ClaRa

The Modelica library ClaRa will be improved during the research project. ClaRa stands for Clausius-Rankine cycle. The source code of the library will be completed by new components and improved with respect to its numerical robustness and validity in special operation modes (start-up, shut down, downtime). Furthermore, the library ClaRa shall be supported by SimulationX in addition to Dymola.

Partner

The following institutions take part in the research project:

Hamburg University of Technology, Institute of Energy Systems, Hamburg, Germany,

NAKULEK - Model-based design and analysis of a natural circulation for cooling of aircraft systems

Nakulek - Model-based design and analysis of a natural circulation for cooling of aircraft systems

In this aviation research project an innovative cooling system for high-temperature heat loads in aircrafts will be developed. Power electronic components shall be cooled by means of a natural circulation and phase change material (PCM). XRG will innovate straightforward simulation techniques to allow a model-driven system development. Thus, the models will be used to optimize the design of the system with regard to essential parameters like weight, power consumption, aerodynamic drag and integration space. New model libraries will provide models for robust simulation of natural circulation using sustainable refrigerants. Both, 1D and 3D (CFD) models shall allow either a system or component simulation for two-phase flows.

Partners

In this joint research project XRG Simulation cooperates with ZAL GmbH (Hamburg’s Center of Applied Aeronautical Research) and the institute of Technical Thermodynamics of Hamburg University of Technology.

Research Funding

The research project Nakulek is supported by the Federal Ministry of Economics Affairs and Energy (number 20Q1519B) and started in July 2016 and will terminate end of June 2020.
