Abstract

This work studied the impinging process of an ice particle on a hot surface. The influences of the impact velocity, the impact angle, and the target surface temperature were studied. The equivalent diameter of the fragments and the volume ratio of adhering fragments were analyzed. The results indicated that, the increase in impact velocity tended to reduce the sizes of the relatively large fragments but promote the generation of more fragments. The target surface temperature had a significant effect on the adhesion of fragments. In this study, the distribution of the dimensionless equivalent diameter of the fragments could be represented by the log-normal distribution. Besides, a new method was developed to extract the volume ratio of adhering fragments. With the increase of the impact velocity, the impact angle, and the target surface temperature, the volume ratio of adhering fragments also increased. Within the scope of the present study, the volume ratio generally ranged from 0.001 to 0.028. Moreover, at

α

= 60.0°,

T_{s}

= 160.0 °C, and

v_{0}

= 58.0 m/s, the volume ratio reached its maximum value. Finally, a correlation for the volume ratio of adhering fragments was developed.

期刊介绍： Cold Regions Science and Technology is an international journal dealing with the science and technical problems of cold environments in both the polar regions and more temperate locations. It includes fundamental aspects of cryospheric sciences which have applications for cold regions problems as well as engineering topics which relate to the cryosphere. Emphasis is given to applied science with broad coverage of the physical and mechanical aspects of ice (including glaciers and sea ice), snow and snow avalanches, ice-water systems, ice-bonded soils and permafrost. Relevant aspects of Earth science, materials science, offshore and river ice engineering are also of primary interest. These include icing of ships and structures as well as trafficability in cold environments. Technological advances for cold regions in research, development, and engineering practice are relevant to the journal. Theoretical papers must include a detailed discussion of the potential application of the theory to address cold regions problems. The journal serves a wide range of specialists, providing a medium for interdisciplinary communication and a convenient source of reference.
