Holographic Mode Shape Investigation of Aircraft Engine Impellers, by cw laser holographic interferometry. The greatest attention was paid to the frequency range from 10 to 15 kHz. A retro-reflective white paint was used for coating the impeller surface which helped to enhance the fringes in real-time/time-average visualization, and to shorten the exposure times i

Study of Shock Wave Reflection in Rectangular Channels by Means of Cranz-Schardin System in Parallepictures of the flow investigated were taken along with a streak record. The interaction of the reflected shock with the boundary layer behind the incident shock wave is discussed. New phenomena have been observed, including the existence of vortices near the closed end of the tube. The formation of

Experience with Laboratory LDA by Measuring Flow Fields in Rotating Turbomachinery,he backscattered Doppler signal, allowing for the measurements of the axial or tangential velocity components up to 600 m/s in the absolute coordinates. Doppler signals between the blade passages are gated and evaluated by a counter. The operation of the system will be illustrated by measurements of

Application of Laser-Dual-Focus Velocimetry in a Counterflow,perimental investigations were conducted in the supersonic 15 × 15 sq cm test section of the ILR. wind tunnel for a main stream Mach number of M., = 2.0 and a total pressure ratio of P./P. = 2.0. The paper briefly describes the flow measurement technique used and brings out the flow field details ma

Measurement of Unstationary Size-Distribution of Submicron Droplets in Rarefaction-Wave Condensatio and condensation by using rare- faction-wave flows of a shock tube. The intensity of light scattered by the condensate droplets was measured at a number of angles circumferentially by photomultipliers with a micro- lens optical-fiber system to be stored in a digital memory bank with high-speed data
