Use of Thermal Imagery to Assess Temperature Variation in Ice Collision Processes

Abstract

The paper describes the exploratory use of thermal imagery on ice collisional processes. This way of measuring provides a new source of information which may lead to new insights and improvements of existing ice collision models. Results indicate significant internal temperature rises in both the crushing case and in the sliding (friction) case. The paper provides some observations, however the main purpose is to show the value of applying thermal imagery in studies of collisional processes. Nevertheless the reader may be interested in the observations originating from the experiments. The first is that the internal temperature increments during ice friction are shown to track the trends in the friction coefficient. The second is that internal temperature increments during ice crushing appear to be concentrated in specific areas of the contact zone and may indicate high pressure zones.
