RESUMO

The flow regimes and interfacial shear stress in helical coil with air-Newtonian and non-Newtonian liquid has been analyzed by developing a dynamic interaction model. The model equation has been developed based on the flow regimes, drag at interface and the wettability effect of the liquid. Also the intensity factor of friction factor of two-phase flow in the helical coil is analyzed and correlated with the dynamic, geometric and physical variables. The functional form of equation appears to predict the pressure drop and interfacial stress satisfactorily for two-phase flow in helical coil with sodium carboxymethyl cellulose (SCMC) solution of different concentrations. The analysis of the model may be useful for further understanding of the complex flow behavior in multiphase flow unit for industrial installation.
