Characteristics and critical heat flux of ice accretion along a fine wire immersed in a Cold air stream with water spray (Effects of temperature and velocity of air stream)

摘要

An experimental study is carried out on the characteristics and critical heat flux of ice accretion along a horizontal fine wire immersed in a cold air stream with water spray. The air stream velocity and temperature range from 3 to 10 m/s and from -5 to -15℃, respectively and the average drop diameter of the water spray is about 0.14mm. To determine the effect of wire diameter on ice accretion, three diameters, namely, 0.5, 0.8 and 1.0mm are selected.
