| Abstract: | To enhance and suppress ice formation around isothermally cooled cylinders in convective water flow, circular fins and heat conductor plates are used, respectively. The heat conductor plates are positioned around each cylinder with some clearance. In the present experiment, the cooled cylinders had a staggered alignment. The experimental results show that the present analytical method for cooled cylinders with fins and heat conductor plates is useful for predicting ice volume under the conditons in which the cooled cylinders are not completely linked by ice in a steady-state condition. It is found that ice accumulation with fins is significantly enhanced compared to that without fins. It is also shown that use of cylinders with the heat conductor plates is effective for suppression of ice formation. © 1998 Scripta Technica, Heat Trans Jpn Res, 26(7): 419–434, 1997 |
