튜브 배열 방향과 수직한 유동에 의한 관외 대류 열전달

초록

Convective heat transfer on the outer surface of tube array perpendicular to the flow direction is experimentally investigated. The test sections which include the aligned and staggered arrangemensts are made and the local heat transfer coefficient on the outer surface of the tube are measured after the flow is fully developed. It is known that the local heat transfer coefficient of the staggered tube arrangement are at most 15greater than that of the aligned tube arrangement.
