Abstract

This paper investigates the effect of viscoelastic force on the focusing behaviour of 5.1µm particles in a straight trapezoidal channel and elucidates fundamentals of elasto-inertial microfluidics dynamic using both experimental and computational approaches. To date, numerous studies have been conducted to improve particle sorting by altering microchannel structures, flow rates and properties of solutions; however, none of these studies have fundamentally investigated the effects of viscoelasticity on particle movements through microchannels with nonlinear cross-section. The results revealed that, at each cross section the inertial lift and elastic forces are unidirectional everywhere except around corners and the channel center which causes the particles to focus in these areas.
