“…This model is based on the three- Predictions from the empirical DCA models are compared with the experimental measurements in Figure 7. The Seebergh and Berg [36] predictions best describe the advancing DCA measurements from the present work. However, this model cannot be applied to receding DCA prediction as it cannot handle negative capillary numbers.…”

“…According to the dynamic contact angle models [22][23][24], the capillary number (Ca), equivalent to the group which represents the relative importance of the viscosity and the surface tension effects (Ψ = / ), was considered as an important dimensionless parameter in predicting the pressure drop. They obtained the appropriate values for the coefficient and the exponents in (12) for dry-plug flows with the polyurethane and Teflon tubes based on their current experiments.…”

A simple approach for calculating the interfacial component of frictional pressure gradient in two-phase flow at microscales is presented. This approach is developed using superposition of three pressure gradients: single-phase liquid, single-phase gas, and interfacial pressure gradient. The proposed model can be transformed in two different ways: first, two-phase interfacial multiplier for liquid flowing alone ( 2 , ) as a function of two-phase frictional multiplier for liquid flowing alone ( 2 ) and the LockhartMartinelli parameter, , and, second, two-phase interfacial multiplier for gas flowing alone ( 2 , ) as a function of two-phase frictional multiplier for gas flowing alone ( 2 ) and the Lockhart-Martinelli parameter, . This proposed model allows for the interfacial pressure gradient to be easily modeled. Comparisons of the proposed model with experimental data for microchannels and minichannels and existing correlations for both and versus are presented.

Abstract. This work presents the comparison between the change of a dynamic contact angle during drop spreading over copper surfaces obtained in the experiment and calculated by using empirical correlations (Bracke et al., Jiang et al., Seebergh et al.). It is found that these correlations are applicable for the case of drop spreading over a smooth surface or over a rough surface into the low capillary number region (2.5·10 -7 ). Dynamic contact angles obtained experimentally increase with increasing capillary number, besides it increases significantly on more rough surfaces. However the calculated values of angles do not depend on Ca.
