Abstract

An experimental study of frost growth under the influence of streamwise vortices in a laminar channel flow is presented. A new model of frost growth is developed to normalize the growth rate of frost with respect to the effects of environmental parameters and time. This normalization and a scale analysis show that the dimensionless frost thickness grows with the square root of environmental time, a single parameter capturing environmental and temporal effects. Experimental plain-channel data obey this relationship to within the uncertainty of the measurements. Also in agreement with the model, the data show no significant dependence on channel location or on Reynolds number (for 5OO
