This is the second report of the subject on which the author reported at the Spring Meeting of the Society in 1971. The previous report deals with the studies on icing on cylinders under the following assumptions : (1) Heat conductivity of ice is so small that conductive heat loss might be neglected in treating icing over a long time ; (2) Ice accumulation on ship occurs at ambient air temperature lower than 0℃ and furthermore in the vicinity of sea surface. Therefore saturated vapour pressure is low and evapolation, or sublimation from ice surface might be hard to occur ; (3) From these points of view, it is considered that all the latent heat quantity of fusion of ice accreted is removed only due to forced convection; and a plenty of water droplets. supercooled as low as ambient air temperature are always in uniform suspension in air stream, in which a cylinder is placed. This paper describes theoretical and experimental studies on icing on plate parallel to or perpendicular to air streamline, in which a plate is placed, under the same assumptions as those for cylinder. Theoretical studies on the "collection efficiency" of plate perpendicular to an air flow, assuming two dimensional potential and continuous stream is also dealt in this paper.
