Internal mass and heat transfer between a single deformable droplet and simple extensional creeping flow

, 2018
This work studied numerically the internal mass/heat transfer of a deformable droplet immersed in a simple extensional flow. The droplet would deform gradually from prolate spheroid to 'peanut' in uniaxial extensional flow, or from oblate spheriod to ...
