Experimental study on the electrohydrodynamic deformation of droplets in a combined DC electric field and shear flow field.

ABSTRACT: A visualization experiment was conducted to investigate the electrohydrodynamic deformation of droplets in a combined DC electric field and shear flow field. Detailed experimental data on both the transient and steady droplet deformation parameters (D) and orientations (ϕ_d ) are provided at R > S and R < S (R: conductivity ratio; S: permittivity ratio) under different electric field and shear flow field combinations. The internal flow characteristics of the deformed droplet were also examined via the digital particle image velocimetry (DPIV) method. Due to the competition of the extensional component (EC) and the rotational component (RC) of these two fields on the droplet, the response of ϕ_d is faster tha
