Looking back: Dresden Science Night 2025

On Friday evening, TU Dresden opened its doors for this year's Dresden Science Night. The Chair of Energy Process Engineering was represented at the Center for Energy Technology (ZET) with a varied program. Numerous interested visitors took the opportunity to experience current research up close and to exchange ideas with scientists.

Energy made visible and understandable

Our aim was to present complex energy processes in a clear and tangible way. With four stations, we were able to offer a wide audience exciting insights into our work:

🔥 Heat transfer: The invisible made visible

An animated video simulating heat exchangers provided an insight into the otherwise invisible process of heat exchange. Visitors were able to see how heat flows through materials and what role flow and temperature gradients play in this process.

💨 Flow demonstrated: Air as a medium

We used an air flow demonstrator to clearly show how air behaves as an energy carrier. The experimental setups illustrated the basic principles of thermodynamics and fluid dynamics - in an understandable and practical way.

🔬 Spectroscopy in the flame

A special highlight was the Bunsen burner with connected spectrometer: Here, visitors could observe live how different elements influence the color of a flame. The colored spectral lines were made visible on a screen - a direct link between chemistry, physics and process engineering.

🌀 Circulating fluidized bed: model in use

Using our model of a circulating fluidized bed system, we demonstrated a process that is used in thermal waste recycling and in the chemical industry, among other things. The impressive movement of the fluidized bed stimulated many conversations about technical applications and energy efficiency.

Hands-on science

We are delighted with the great interest and the many stimulating discussions at our stations. The questions and enthusiasm of the visitors confirm how important direct dialog between science and the public is - especially when it comes to such a central topic as the energy supply of the future.

Many thanks to our entire team, who contributed to the success of this evening with their great commitment and expertise.

We are already looking forward to the next Dresden Science Night - and to being able to show once again how exciting energy process engineering is.
