Abstract

A numerical analysis of ice crystal growth on cold surfaces A.Z. §ahin Department of Mechanical Engineering, King Fahd University of Petroleum & Minerals, 60^2 ABSTRACT A numerical study of ice crystal growth is presented. The ice crystal is as- sumed to grow in either cylindrical or spherical shape. The models permit a continuous determination of the phase change interface and the temper- ature distribution. A finite difference approach is used to solve the model equations. Numerical results are compared with available theoretical and experimental data. The effect of the velocity, ice crystal base temperature and biot number are considered for the determination of the growth rate of the ice crystal. INTRODUCTION It is well known that when humid air is exposed to a solid surface which is colder that the dew-point temperature of the air, condensation will take place as the air is cooled, and that the water vapor leaving the air will pass directly from ga
