Goals and Perspectives

The objective of the workshop is to bring together scientists from universities, research centers, and industry with interests in computational and mathematical modeling for the design of solar tower power plants. This workshop serves as platform for the exchange of knowledge, to intensify existing cooperation, to make new contacts, and to initiate new cooperation for future projects.

The workshop consists of sessions of contributed talks covering various aspects of the field. A special effort will be made to enable young scientists to attend the workshop and to meet and interact with the more senior researchers. This will be achieved by allowing ample discussion time following each talk, and through an extensive poster session by which young scientists can demonstrate and discuss their research with invited speakers and other attendees.

The workshop language is English.



For registration please write an email with your name, organization, and number of participants. Attendance is free.

Last day of registration is June 29, 2017.

The event takes place in the Ford hall of the SuperC building at RWTH Aachen University (Templergraben 57, 52062 Aachen).

We have designed the program to allow for ample discussion time with invited speakers:

  • After every talk, there are 10 minutes reserved for discussion.
  • Additionally, during the two coffee breaks and the lunch break there is time to meet and discuss.

For students this can be used to establish new contacts, and to find interesting bachelor or master theses in the field of computational engineering of solar thermal power plants.
