Characteristics of In-Tube Condensation Heat Transfer and Pressure Drop in a Spirally-Twisted Tube and an Internally-Finned Tube
나선형비틈관과 내부핀부착관에서의 관내 응축 열전달 및 압력강하 특성
Abstract
An experiment was carried out to evaluate the heat transfer and pressure drop performances of the smooth tube and two augmented tubes using R-113 under horizontal condensation condition. The augmented tubes are a spirally-twisted tube and an internally-finned tube. The test tube is 13.88 mm in diameter and 3.2 m long. Five different inlet pressure of 0.13, 0.16, 0.18, 0.21 and 0.23 MPa were employed and the mass flux was varied from 80 to 265
