Do you know how Simulation Technology has the ability to investigate many flow challenges which can introduce light into our assumptions regarding the movement of fluids and heat transfer throughout a space?
Our two presenters have had considerable expertise in the field of simulation technology through CFD and presented such parameters.
Dr Colin Allison (PhD) from Simultude explained aspects of CFD involving calibration of CFD models with test data, examples of CFD applications and advantages of this technology over the high cost of wind tunnel testing. His CFD data consistently showed how close simulation data was to the data given out by manufactures and wind-tunnel testing.
The software he uses is FloVENT for HVAC applications (Simplified object geometry eg cuboids, cylinders and prisms etc) and FloEFD; a generic CFD code using Solidworks geometry (Highly accurate research and scientific investigation tool).
Colin has used CFD for pressure-drop over louvres, determining effectiveness of composite insulated panels, wind induction simulation and many other applications. But of particular interest was his work with Airius.
John Brodie of Airius (Oceania) P/L discussed, from an air moving technology distributor point of view, his experience with CFD to demonstrate how their patented air turbine technology assists in cooling, heating, the saving of energy and replacement of A/C ductwork within a multitude of installations and spaces.
Several examples were given with particular interest in the ‘Arius Air-Pear’ fans which were used in large warehouse/supermarket/sporting or many other large complexes minimising the need of ductwork for air distribution.
Generally, the fans were placed vertically for winter in order to counteract stratification and horizontally in summer to minimise dead areas and temperature variation in the space through air circulation.
CDF was used to determine the locations and angles required to maintain even and acceptable temperatures at required location above floor level.
Big bonusses were the outcome –
Reduced capital cost.
Reduced energy costs.
Reduced maintenance costs.
Increased comfort levels.
Stable air distribution and temperatures.
