Seven different solid particles having the same volume were circulated in the heat exchanger. The effects of various parameters such as water flow rates, particle geometries, materials, and corrugated tube geometries were investigated. The present work showed that the higher thermal capacities of materials and the geometries closer to the spherical one have higher heat transfer performances. In addition, heat transfer coefficients in the corrugated tubes were a little higher than those in the smooth tubes. 대한설비공학회 파형관을 갖는 수직형 순환유동층 열교환기의 열전달 Heat Transfer in the Vertical Type Fluidized Bed Heat Exchanger with Corrugated Tubes Article 2 설비공학 논문집, v.16, no.12, pp.1149 - 1155 설비공학 논문집 16 12 1149 1155 kci ART000929844 Vertical type fluidized bed heat exchanger Solid particle Counterflow Heat transfer coefficients Vertical type fluidized bed heat exchanger Solid particle Counterflow Heat transfer coefficients 수직형 순환유동층 열교환기 고체입자 대향류 열전달계수
