Mass transfer correlation development for the presence of entry region coil as swirl promoter in tube

Model development for mass transfer correlation in the presence of entry region coil as swirl promoter in tubes was presented in this paper. Coils were tested within a geometrical pitch 0.015, 0.025, 0.035 m and coil length 0.065, 0.095, 0.125 m. The electrolyte was equimolal Potassium ferricyanide, Potassium ferrocyanide and excess sodium hydroxide. The mass transfer correlation is based on law of the wall similarity. A model was developed in terms of geometric parameters and presented.g¯=3.14×108[Rem+]−0.006(PcD)−0.17(LcD)−3.04(Lccl)3.06
