Title:A Study of Frost Formation on a Plain Fin
Author(s):Robinson, C.M.; Jacobi, A.M.
substrate energy
frost growth
Abstract:Frost growth on heat exchanger surfaces in refrigeration and air conditioning systems has posed a challenge to heat transfer engineers for decades. Frost buildup causes an increase in the airside pressure drop and thermal resistance, yielding a substantial decrease in operational efficiency. Significant prior work has been aimed at understanding frost growth on a flat plate, but little research has been done to investigate leading-edge and trailing-edge effects on frost formation. The focus of this research is on extending existing models of frost growth to include these effects. The new model predicts frost thickness, frost density, and interface temperature for a fin under specified thermodynamic conditions. The model predictions are compared to experimental data, and the model is found to predict the data to within the measurement uncertainty.
