High Deborah number flows through 3D contractions at the microscale

Oliveira M.S.N., Afonso A.M., Pinho F.T., Alves M.A., FEUP - Faculdade de Engenharia da Universidade do Porto, PT

In this work, we report a rich sequence of elastic transitions captured experimentally using a solution of polyethylene oxide in a water/glycerol mixture that exhibits shear-thinning and viscoelastic behavior. The experiments were carried out in [...]

Design of Optimized Microfluidic Devices for Viscoelastic Fluid Flow

Alves M.A., Universidade do Porto - Faculdade de Engenharia, PT

In this work we present a fully automated procedure for the design of microfluidic devices with optimal performance. The proposed approach combines an in-house finite-volume viscoelastic flow solver, an optimizer, and an automatic mesh generation [...]
