The AEE - Institute for Sustainable Technologies was founded in 1988 in Austria as a non-university research institute focused on renewable energy and resource efficiency. It conducts research, development, consulting and training. It has 65 employees including master's students, PhD students, and staff. The institute has several research departments focused on areas like thermal energy technologies, industrial processes, building and retrofitting, and monitoring labs. The document discusses a pressure loss model for T-pieces that the institute developed using experimental data in order to make it openly available so it can be used for hydraulic analysis and applications like solar collectors. The model is published under an open license so it can be used and adapted by others.

Who needs T-piece pressure losses?
hydraulic
analysis
CFD
very expensive
à not feasible for many
engineering tasks
Bernoulli models
need to model
small-scale effects
e.g. pressure losses of T-pieces

Data model
Original data
• need to be calibrated and filtered (25.000 data points)
• requires knowledge of the experimental setup and conduct
• are only available for discrete points, not easily generalizable
• are therefore not directly useful for calculations!
This is why we publish a full data model
• Best way to access the information hidden in the data
• Allows arbitrary queries à useful for calculation tools
• Straightforward to use, no need to bother with model details
• Format: Matlab toolbox = simple distribution, simple installation
• Other options available on request (Python, Java packages etc.)

Perspectives
Use of our data (model) in hydraulic calculation tools
• solar energy, collector fields
• collector design
• thermal networks / district heating etc.
• possibly any other flow situations where parallel flow occurs
Collaboration
• Information exchange with other institutes & companies (models,
components etc.)
• Creation of new R&D ideas and projects
• Reduced target audience, high success chance
