3-D Velocity Fields Measurements of Propeller Wake Using a Stereoscopic PIV
Stereoscopic PIV기법을 이용한 프로펠러 후류의 3차원 속도장 측정
Abstract
The objective of present paper is to apply a stereoscopic PIV(Particle Image Velocimetry) techiique for measuring the 3 dimensional flow structure of turbulent wake behind a marine propeller with 5 blades. It is essential to measure 3-components velocity fields for the investigation of complicated near-wake behind the propeller. The out-of-plane velocity component was measured using the particle images captured by two CCD cameras in the angular displacement configuration.400 instantaneous velocity fields were measured for each of few different blade phases of
