Dynaflow Research laboratory

Testing of materials and products is important for quality control purposes. Our Dynaflow Research Laboratory is equipped to test various mechanical and physical properties specifically important for the quality of fiber reinforced plastic material. In house testing capabilities, amongst others, consist of:

  • Tensile testing machine Testometric X500-50 (50kN)

  • High temperature oven for LOI Glass Content Testing

  • Barcol hardness measurement.

  • Optical microscope testing

European Research Project - GEOTHERMICA

GEOTHERMICA is a European project to promote research and innovation in geothermal energy to make geothermal energy reliabe, safe and cost-competitive. GEOTHERMICA combines the financial resources and know-how of 20 geothermal energy research and innovation programme owners and managers from 16 countries and their regions. 

A multinational consortium of geothermal experts has launched a GEOTHERMICA project to develop a new glass fiber reinforced epoxy casing system for geothermal application, short GRE GEO. The casing system shall be used in new installations as well as utilized for workover for old wells. Furthermore, the project will include the guidelines and tools for the design, qualification, and installation of the GRE piping system.

DRG has been developing advanced engineering software products for many years. Our main products are our pipe flow analysis tools BOSfluids, BOSpulse, our piping model builder ISOtracer, and our research-oriented numerical software library Jive. DRG is also a vendor for several other CFD and Finite Element software packages.

The engineers at DRG, including our software engineers, use our software products on a regular basis for solving a wide range of challenging problems. This means that we constantly get feedback that helps us developing software products that meet the expectations of its users. 

This also means that we can provide expert support to the users of our software products.
