The flow visualization in vicinity of stationary and rotating cylinder and wing with rotor-type slap were performed for flow velocity range from 1 to 7 mps. The modified method of smoking wire and laser sheet was applied. DPSS-laser (KLM-532-300) with external control of radiation modulation was used for illumination. The executed investigation allowed to implement verification of flow simulation data by finite element method obtained by StarCD and ANSYS CFX-software.
