The analysis is fared based on the Lockhart-Martinelli Model. The Lockhart-Martinelli Model is modified and incorporated to predict the frictional pressure drop of air-non-Newtonian liquid flow in vertical helical coil. The effects of operating variables, such as phase flow rates on frictional pressure drop are investigated. To predict the frictional pressure drop, friction factor of gas-liquid 2 phase flow, correlations have also been developed for different flow regimes, as a function of different dimensionless groups by introducing the operating variables and physical properties.
