The performance of a fan or turbine depends on the shape of its blades. However, it is challenging to experimentally develop energy efficient products because of the difficulties studying the details of how air passes through the fan or turbine. Sophisticated instrumentation is required to physically measure air velocities, temperatures, and pressures.
A fan or a turbine can be numerically simulated in a computational fluid analysis. Airfoil shape, casing design and clearance effects can be studied simultaneously. The impact caused by changing the geometry can be examined because SC/Tetra simulates pressure, flow rate and flow pattern over the airfoil.
