Abstract

This study deals with the critical heat flux of ice accretion along a horizontal fine wire immersed in cold air stream with water spray. Experiments are carried out to investigate the effect of droplet diameter, wire diameter, air velocity and air temperature on the critical heat flux. Present results reveal that critical heat flux is markedly affected by both the droplet diameter and the wire diameter. In this study, the effects of four parameters (droplet diameter, wire diameter, air velocity and air temperature) on the critical heat flux are quantitatively determined, and a non-dimensional empirical equation that correlates the critical heat flux and above parameters has been obtained.
