Abstract In order to analyze the temperature distribution of unsteady frost layer for finned - tube vaporizer numerical sim-
ulation technology was adopted to calculate several sets of influence factors. Through index model and multivariate linear regres-
,
sion model a formula of the temperature distribution was fitted. The result shows that the overall mean square error of fitting val-
,
ue is less than 10% . The fitting formula is sufficiently precise and can be used in the field of engineering calculation.
