The Institute of Solar Research of the DLR conducts research into the technical and economic optimization of solar thermal energy generation at four different locations in Germany and southern Spain. The research and development activities are always application-oriented and close to industry. Our international team consists of highly qualified specialists and engineers who love and enjoy their work.
The technology of producing high-temperature working fluids from solar energy has great potential for use. The porous absorber as a receiving element plays an important role in this technology. The efficiency of solar radiation absorption and heat transfer to the working fluid depends on heat and mass transfer processes in the porous medium, which must be controlled. Knowing the actual convective heat transfer coefficient plays a crucial role in the accuracy of calculations. The convective heat transfer coefficient is found using the Nusselt criterion equation, in which the coefficients for new designs are determined using an experimental setup. To achieve maximum efficiency in the calculation of porous absorbers, the standard Nusselt criterion type setup should be modernized. We offer you to develop a scheme of such an installation.
As part of your master's thesis, you will develop and design an experimental setup to study convective heat transfer in a porous medium. The results of your work will allow you to optimize the geometric design of the porous absorber and significantly increase the thermal efficiency of the CSP receiver.
You will be closely integrated into our diverse and highly motivated research team located in Jülich and Köln. The work will be supported by the Institute for Solar Research, leading experts in concentrated solar technology. An experienced colleague will support you throughout your master's work. The tasks and work schedule will be agreed with the responsible professor at your university. For FB4 students at RWTH Aachen University, the thesis can be defined as internal and can be supervised by a DLR professor who has a chair at RWTH.
Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalleled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (f/m/x).Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
