What is it about?
Entry region swirl promoters gain importance in industry because of its effectiveness in augmentation of mass and heat transfer augmentation. Design of equipment needs momentum transfer data along with mass or heat transfer data. Hence an experimental investigation was carried out with coaxially placed entry region spiral coil as turbulence promoters on momentum transfer in forced convection flow of electrolyte in circular conduits.

Why is it important?
The study comprises of evaluation of momentum transfer rates at the outer wall of the electrochemical cell. The objective of this work is to obtain higher momentum transfer coefficients in an electrolytic column using entry region coil assembly as turbulence promoter in augmentation technique. My effort is made to acquire higher augmentation rate with lower frictional losses and high efficiencies. It may lead to the construction of energy efficient transfer operation.
Perspectives
I hope this article is envisaged obtaining momentum transfer data at the inner wall of annular conduits along the length of the column. Local momentum transfer data were obtained and the results were reported. These results could be adopted for enhancing mass transfer processes like electro dialysis, ultra filtration, reverse osmosis and several other processes and reported increased transfer rates. The electrochemical processes like electro winning, electro refining, electro milling and electro organic synthesis could employ swirl generating promoters to obtain higher transfer rates. The article would be useful for the development of energy efficiency in momentum transfer equipment.
