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 Guitar Straps 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 presented article, velocity fields of CRF placed in AEG HKB75540NB 75CM FLAMELIGHT 5 BURNER GAS ON AUTOMATIC IGNITION GLASS HOB a rectangular channel was measured, using Laser Doppler Anemomentry (LDA) method and thermoanemometric probe (TA).
