Dynaflow Research Group is a firm which specializes in the advanced end of the engineering spectrum. Our work often requires a multi-disciplinary approach: encompassing the static and dynamic analysis of both fluids and gases, and mechanical components. We believe that we are at our best when creative thinking and a practical approach are required to tackle a problem.

Fiberglass Piping

In Short

The last decades have seen a large growth in the use of Fiber Reinforced Plastic (FRP) piping.

The advantages of FRP piping compared to traditional steel piping are the superior corrosion resistance as well as considerably lower weight.

DRG has been involved in R&D of many different Fiberglass applications for various suppliers, users and research institutes. DRG is a founding member of the ISO14692 committee, the DNV Committee for certification of fiberglass craftsmanship and is (co-)author of many technical papers and code contributions.

Flow Analysis

In Short

DRG has more than 20 years of experience in solving water hammer and pulsation problems. To solve these problems and prevent process lines from malfunctioning, DRG has developed BOSfluids and BOSpulse. These professional software solutions can be used to prevent surge damage caused by water hammer, air entrapment, inadequate surge vessel sizing or filling-up a pipeline.

Upstream and downstream process lines often involve mixtures of fluids that may consists of multiple phases as well. DRG has a long track record in solving problems associated with the occurrence of multiphase flows, which often consist of water, oil, gas and sand particles using Computational Fluid Dynamics techniques.

Risk & Hazard Assessment

In Short

Most industrial licensing authorities and insurance companies require operating companies to carry out hazard studies and risk assessments during the design of facility, as well as prior to construction and during operation.

HAZOP study is a well-proven structured team-based method for hazard identification at process design completion or for planned modifications.

Pressure & Thermal Equipment and Piping

In Short

The fields of Pressure & Thermal Equipment and Piping encompass all process and power piping, buried or above ground, pressure vessels, boilers, tanks and much more.

The piping may be subject to a feasibility study or studies during the design phase, but even more challenging are those piping systems that are part of the revamp of an existing plant to maximize output. Flow-related problems such as slugging, surge-related phenomena and cavitation can also put severe loads on the piping.

Pressure vessels, boilers, tanks, etc. can be, apart from the common pressure and thermal loads, subject to severe thermal gradients during start-up conditions, highly cyclic loads giving rise to fatigue, and also dynamic environmental loads such as wind and seismic activity.

Dynaflow Research Group can analyze these problem types by selection of the most suitable software from a wide range of available software packages. Code calculations and finite element analyses (FEA) can be performed for Code compliance.

Pulsations and Vibrations

In Short

DRG has a proven track record in pulsation studies for pumps and compressors, as well as assisting our customers with other flow induced vibration projects. We have conducted a broad spectrum of projects ranging from pulsation studies, anti-surge analysis for compressor emergency shut-down, flow induced vibrations and piping flexibility and failure studies for the vacuum insulated piping.
