산업용 전동기 내부 유동 해석

The present study aimed at clarifying unsteady flow characteristics of the industrial motors. High- resolution CCD camera(2k×2k, ES 4.0) and Nd-YAG laser are adopted to clarify flow characteristics of the motor. Quantitative velocity distribution and related flow information is presented and macro flow structure, generated via the motor axis and the cooling fan, also is investigated. Moreover, from the velocity field data, discharge flow rate through the air duct is compared at each measuring sections.
