Effects of the Inner Cylinder Diameter and the Initial Temperature of the Fluid on Free convection Heat Transfer in a Stably Stratified Fluid between Coaxial Cylinders (An Study on the Case of the Inner Cylinder Diameter Being Small)

摘要

The stratified layer was formed using a sucrose aqueous solution and was heated from the outer cylinder (70mm I.D.) at constant heat flux and cooled from the inner cylinder (15mm O.D.) at constant temperature. It was found from the experimental results that when the initial temperature of the fluid T{sub}0 is between heating and cooling temperatures (T{sub}c
