Abstract: |
On the basis of molecular diffusion Fick′s law and principles of energy and mass conservation,a simplified model of frost growth on a surface is presented.Numerical calculation shows that the model can predict the regularity of frost growth with reality.It is in accord well with existent experimental data and other theoretical models |
