Project GeoHex has completed a successful first year!
Kick-started in November 2019, the project is an international initiative funded under the EU’s Horizon 2020 programme (Grant agreement 851917), to explore opportunities to improve anti-scaling and anti-corrosion properties as well as heat transfer performance of the heat exchanger (HX) material that could lead to smaller, more efficient and economical systems in the geothermals.
The consortium is pleased to announce the publication of its second issue, November 2020. Click here to find out more about:
GEOHEX TO EVALUATE HEAT TRANSFER PERFORMANCE VIA TEST RIGS
Customised rigs have been designed to test single-phase heat exchangers and evaporative heat exchangers to assess the influence and effectiveness of particular surface treatments on heat exchange. Discover more
IMPROVING HEAT TRANSFER PERFORMANCE OF HEAT EXCHANGERS
Hygrophobic coatings are being considered in the GeoHex programme to enhance the heat transfer performance of geothermal heat exchangers, and the programme will consider the modification of surface energies as well as micro or nano structuring to achieve hygrophobic surfaces. Discover more
PLASMA SPRAY COATINGS FOR GEOTHERMAL APPLICATIONS
Under the GeoHex project, we will perform the suspension and solution precursor-based plasma spray for different coatings such as TiO2, CuO, Fe3O4, and TiO2/Al2O3 composite coatings with varied concentration of Fe doping, which will improve the efficiency and lifetime of geothermal heat exchangers.
