TEMPORAL INSTABILITY OF NON-NEWTONIAN LIQUID JETS DURING CENTRIFUGAL ELECTROSPINNING

ABSTRACT

This investigation is aimed at analysing linear instability of an initial stable jet through the air-sealed electro-centrifugal spinning process which is significant in creating nanofibers. Utilising the perturbation theory to diminish the governing equations, into a 1-D mode with the option of solving acquired non-linear differential equations. Hence, the trajectory of a power-law fluid jet during electro-centrifugal spinning power has been determined. Dispersion relation has been gotten from the linear theory to study the conduct of a power-law fluid curved jet with an electric field.
