Drop formation in non-Newtonian fluids

Though most of the industrial fluids show non-Newtonian characteristics, the drop formation studies in them have not been reported. The results will very strongly depend on whether the non-Newtonian fluid forms the dispersed or continuous phase. 

Experiments have recently been conducted by Saradhy and Kumar (SI) for drop formation of benzene in a C.M.C.1 solution which followed the 

Xn is not known rigorously, but its upper and lower bounds have been calculated (W2). 

From Eqs. (144) and (145) and the definition of CD, the downward resisting force becomes 

Introducing the above drag expression Eq. (146) in the force balance particle equation of unified model (K14), we obtain

The very important field of bubble and drop formation in non-Newtonian fluids remains virtually untouched, even in the absence of heat and mass transfer and chemical reactions.
