Project InsiSt completed
IThe ‘InsiSt’ project, funded by the State of Bremen as part of the State Programme for the Promotion of Research, Development and Innovation (FEI) of the Senator for Economic Affairs, Labour and Europe of the Free Hanseatic City of Bremen, was completed this month. The aim of this project was to prove that the method for in-situ measurements of thermal conductivites improved by FIELAX is comparable to the established standard according to ASTM D5334. To this end, experiments were carried out in which so-called needle probes were inserted into the same undisturbed sample as the sensor string used by FIELAX. The measurements were carried out in different materials: 1. in water-saturated sand and 2. in water “stiffened” with gelatine.The results are currently being prepared for publication.
Thermal Testing – new brochure
Our new brochure ‘FIELAX In-Situ Thermal Testing’ describes how we measure in-situ temperatures and calculate thermal conductivities as well as different fields of application. Simply download it here.
New publication on the variability of thermal conductivities
As part of the project "WEGNordOst", which is funded by the state of Bremen within the framework of the state program "Promotion of Research, Development and Innovation" (FEI) of the Senator for Economics, Labor and Europe of the Free Hanseatic City of Bremen, we have published some of the results together with our cooperation partners from the University of Bremen and the University of Kiel. The publication is available at: https://link.springer.com/article/10.1007/s11001-023-09531-2 and describes the sediment temperatures and thermal conductivities of coastal sediments in the German part of the Baltic Sea / Eckernförde Bay.
WEGNordOst – Update
As part of the "WEGNordOst" project, which is funded by the state of Bremen under the state program "Promotion of Research, Development and Innovation" (FEI) of the Senator for Economics, Labor and Europe of the Free Hanseatic City of Bremen, we are investigating the interaction between temperature and thermal conductivity in gas-bearing sediments. For this purpose, we conducted measurements in the Eckernförde Bay (Baltic Sea) with the research vessel ALKOR in November 2022 and April 2023. We were able to collect a lot of interesting data, the analysis of which will keep us busy for a while. Read more
