CFD Problem Solving

GAIM is the research and development division of The Greenbank Group UK. It focuses on the development of new products, and works on a consultation basis with other divisions of The Greenbank Group to develop new opportunities for the System product portfolio.

One of the main driving factors in establishing GAIM was to provide a problem solving service for customers, whereby through scientific investigation our engineers can help provide solutions in areas such as pneumatic conveying, combustion, de-dusting, heat exchangers and erosion problems.

GAIM’s relationship with several of the UK leading universities allows it to perform detailed experiments and carry out experimental research on certain scenarios. GAIM has access to a 1/3rd scale and a 1/10th scale pneumatic conveying rig.

It also has other rigs developed for other power station technologies. GAIM specialises in laser-based measurement such as Particle Image Velocimetry and Laser Sheet Visualisation, both techniques are being adapted for industrial use. It is also able to focus on a range of other measurement techniques.

Computational Fluid Dynamics (CFD)

One of GAIM’s major tools is Computational Fluid Dynamics (CFD). CFD programmes are similar to finite element programmes but for fluid systems. The programmes allow simulation of fluid field variables such as pressures, velocities and temperatures. The programme is also able to undertake particle tracking and chemical reactions (such as combustion). CFD has been used to identify the optimum positions for their VARB devices in pipe networks. CFD is used in a wide range of industries and its based equations have lots of good correlation to experimental and empirical data.

One of GAIM’s major areas of interest is instrumentation and measurement. GAIM is particularly interested in developing new and more accurate ways of measuring properties and values within harsh or difficult environments. GAIM will be happy to investigate customer’s measurement problems and work on solutions to address these problems.

The research done by GAIM for their customers has lead to the installation of several tailor made solutions. Of particular note are the VARB devices that are designed and positioned based on investigation by GAIM engineers. Each scenario is thoroughly investigated and solutions tested experimentally and computationally. This approach has been found to be incredibly successful.
