Computational Fluid Dynamics
Computational Fluid Dynamics (CFD) is a tool to analyze and solve problems that involve fluid flows. The fluid motion and heat transfer are solved using numerical schemes. CFD is applied to a wide range of research and engineering problems in many fields and industries. Dynaflow Research Group has years of experience in applying advanced CFD techniques. Many of our engineers have obtained an MSc or PhD using Computational Fluids Dynamics.
Using Computational Fluids Dynamics, accurate predictions can be made concerning the flow properties of complex systems. This can be applied to pipe line component interferences, separation systems, mixers or heat exchangers. Furthermore, CFD models are easily revised and can offer many detailed insights into the flow physics. At Dynaflow Research Group we use Helyx-OpenFOAM for our CFD studies. After a thorough discussion with the client over the CFD analysis results; realistic mitigations will be proposed to improve the systems’ reliability, safety, and performance.
DRG supports its clients with Computational Fluid Dynamics for various applications. CFD experience at Dynaflow Research Group includes, but is not limited to:

Heat exchanger performance analysis
Multiphase flow is another domain where Computational Fluid Dynamics can aid in the design optimization of components. Systems containing multiple phases, like slug catchers, are difficult to capture in current 1D flow solvers, due to the three-dimensional nature of the flow. For these kinds of systems, CFD can help to provide an accurate insight into the fluid behavior.
In order to design a high performance ﬁnger-type slug catcher for example, it is necessary that the ﬂuid ﬂow in the inlet header manifold is evenly distributed among the diﬀerent ﬁngers. Using Computational Fluid Dynamics, diﬀerent conﬁgurations can be deﬁned and compared using the time-averaged mass ﬂow at the ﬁnger inlets. The initial conﬁguration, leads to a large misdistribution in time-averaged mass ﬂow. Dynaﬂow performed an optimization study using Computational Fluid Dynamics. Increased pipe diameter was found to promote the mass ﬂow balance. Additionally, by applying an extra split in the main header pipe, the equal ﬂow distribution was signiﬁcantly increased.

Other Complex Flow Analysis Applications
Computational Fluid Dynamics analyses are not limited to the subjects discussed above. Many more applications are possible and are well represented in our project portfolio. These include heat transfer in burners, interference of pipe line components such as filters, valves pump inlet/outlet etc. and flow inside pumps and compressors.
For all of the complex flows discussed before, a number of types of analyses can be performed. These include:
- Optimizing design to improve performance,
- Validating initial design performance,
- Determining the cause of performance issues or failures,
- Feasibility study of new configurations, e.g. closely spaced filters or pumps,
- Fluid structure interaction analysis to solve the interaction of some movable or deformable structure with an internal or surrounding fluid flow.
