좁은 핀이 달린 경사면을 흐르는 리튬브로마이드 수용액에서의 열 및 물질전달

초록

This paper describes a numerical analysis of absorption of water vapor into LiBr-H2O solution flowing over a finned inclined surface. The momentum, energy and diffusion equations are solved numerically using a finite difference method. The various shapes of the wall surfaces are considered to find the best shape for absorption. Also, the effects of the interval of fins and Reynolds numbers are investigated. It is assumed that the wall temperature and the surface tension are constant. The parabolic surface shows better water vapor absorption than other surfaces. Water vapor absorption increases graudally with the decrease of the Reynolds numbers and the interval of the fins.
