배플 플레이트 크기에 따른 관내의 유체유동 특성 및 열전달 특성에 관한 실험적 연구

An experimental study on fluid characteristics and heat transfer characteristics along a horizontal circular tube by baffle cut rate

  The object of the experimental is comparing that changing Baffle cut rate, fluid velocity in the channel and changing flow temperatures, behaved experimental study to investigate fluid characteristics of interior, pressure drop characteristics and heat transfer characteristics by PIV system and heat transfer experimental.   In this experimental, baffle cut rate is 30%, 40%, 50%, velocity is 0.5㎧, 1.0㎧, 1.5㎧ 2.0㎧ and heat temperature is 50℃, 40℃, 30℃, cooling temperature 5℃. PIV system determine velocity characteristics, turbulent intensity, kinetic energy and pressure drop.
