Comparison between theoretical models and experimental data for the spreading of liquid droplets impacting a solid surface

Predictions for the spreading ratio of an impinging droplet have demonstrated much uncertainty in the mechanics of impacting droplets. Theoretical models tend to overpredict the maximum spreading ratios, and predicted times for the spreading process are significantly different from experimental data...

Summary:Predictions for the spreading ratio of an impinging droplet have demonstrated much uncertainty in the mechanics of impacting droplets. Theoretical models tend to overpredict the maximum spreading ratios, and predicted times for the spreading process are significantly different from experimental data. The Kurabayashi-Yang equation provides the best estimate for the maximum spreading ratio although it could not be used to predict transient spreading. The majority of the differences between its predictions and experimental values was within 10%.
