An attempt to measure cycloidal rotor fan in a rectangular duct

wuh721414ale6l1 A fan with cycloidal rotor (CRF) becomes a popular idea in wide application such as aviation, HVAC (heat, ventilation and air conditioning) or marine propeller systems.This is due to advantages such as direct control of the flow direction, larger flow rates than in a conventional machines without cycloidal control.In the superman headband presented article, velocity fields of CRF placed in a rectangular channel was measured, using Laser Doppler Anemomentry (LDA) method and thermoanemometric probe (TA).
