Comments on 'Two-phase frictional pressure drop of gas-non-Newtonian liquid flow through helical coils in vertical orientation'

摘要

Biswas and Das [1] carried out investigations to evaluate the two-phase frictional pressure drop for gas-non-Newtonian liquid flow through helical coils in vertical orientation. The researchers performed their experiments using nine coils and four different non-Newtonian liquids. They illustrated the effects of gas and liquid flow rate, coil diameter, and liquid properties on two-phase frictional pressure drop. Also, they presented comparison between predicted and measured values of the frictional pressure drop for different methods such as Eisenberg and Weinberger [2] correlation, Aoki [3] correlation, Davis [4] correlation, and Xin et al. [5] correlation.
