PREDICTION OF PRESSURE DROP IN HELICAL COIL WITH SINGLE PHASE FLOW OF NON-NEWTONIAN FLUID

Abstract

The pressure drop of single phase was studied experimentally with non-Newtonian fluids of Carboxy Methyl Cellulose (CMC). Single helical coil with five different helix angles were used in this study to identify the effect of helix angle on pressure drop. The effect of helix angle is significant in moderate and high generalized Dean’s number of laminar region. The effect is insignificant in low generalized Dean’s number range and turbulent region. Correlations were developed for predicting the frictional pressure drop in laminar and turbulent regions.
