Gas-liquid flow through helical coils in horizontal orientation
Experimental investigations have been carried out to evaluate the two-phase pressure drop and the holdup for gas-Newtonian liquid flow through helical coils. 24 helical coils and three different liquids were used for the experiments. Empirical correlations have been developed to predict the two-phase friction factor and the liquid holdup as functions of various physical and dynamic variables of the system. Statistical, analysis of the correlations. suggests that they are of acceptable accuracy.
