Process & Energy

In the Process and Energy sector we have used CFD for a wide range of applications; Combustion simulation for boilers, product development for process equipment like pumps, mixers and heat exchangers, HVAC design for clean rooms to car parks and full scale hazard analysis for evaluate environmental impact on plant accidents. All cases have their individual flow related challenges that can be address and improved by the means of CDF.

Separators

Improvements in computational fluid dynamics techniques have created a unique opportunity to optimize highly complicated multiphase flow process devices such as feed water heaters or cyclones.

HVAC units

Feed water tanks

The boiler feed water tank and its optimal use are essential elements of boiler functioning in the power industry. With the help of CFD simulation and FEM techniques it is possible to optimize and design various sizes of feed water tanks, otherwise known as deaerators or degassing towers. The optimization of the feed water heater tanks reduces vessel weights and achieves the best possible performance for deaerators.

Cyclones

The industrial cyclones often have erosion, high pressure drop and low performance challenges. In addition to the equipment plant restoration, the usage of numerical FEM and CFD techniques can significantly decrease troubleshooting time and increase the industrial plant’s efficiency.

Mixers/Reactors/Rotating machines

The flow and mixing dynamics of mixers or bioreactor (e.g. used in chemical plants or sewage cleaning system) can be well analyzed using CFD techniques. Various comparisons are performed in the research for different intake nozzle locations, multiphase masses, particle or bubble sizes, shell and baffles geometries and mixing multiphase process age. By analyzing the effects of these variations the flow, mixing- and rotational dynamics may have been optimized. Such a CFD technique can be evidently used for many similar industrial processes that are using complex flows such as liquid particle suspension.

HVAC units

Industrial HVAC systems can be easily analysed using CFD techniques in order to optimize energy usage, fresh air age, ventilation behaviour or burning gas exhaust ventilation in case of fire. Moreover, food industries can get benefit of the CFD for design and volume optimizaion for their storage or warehouse areas
