Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter-sized alginate hydrogel beads. [PDF]
Abstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation. Next, we measured the perimeter and circularity of hydrogel beads as

Numerical investigation of the effect of nanoparticle sedimentation on the thermal behavior of cavities with different cross-sectional shapes [PDF]
In this paper, the thermal behavior of nanofluids was numerically simulated during nanoparticle sedimentation. A new solver was developed in the open-source framework, i.e. openFoam, using the finite volume method by combining appropriate solvers.
