Abstract
The evaluation of the shear stress over a layer of cells in a
micro-channel was predicted by means of computational fluid dynamics.
The lower surface of a parallel-plate flow channel was seeded by
simply shaped cells, modeled as rigid hemi-spheres and hemi-ellipsoids.
Numerical simulations were performed, at low flow regime, to
compute the shear stress distribution on the surface of the cells for
investigating the relationship between the shape, the relative distance
among the cells themselves and the stress acting on them. A comparison
of the obtained results allowed to describe the particular fluidic
patterns experienced by cells, taking into account that the related
mechanical stimulation can determine and/or modulate the activation
of the chemical and physical response. Moreover this modeling
approach can be useful to study cell-cell interactions under different
fluid dynamic conditions and adhesion sites in order to investigate
specific cell functions.

The XVIII edition of the SIR conference will be held in Villa Rosa, a recently renovated ancient Neapolitan villa in Capri Island (Naples, Italy), in September 12th-14th 2024. The event will be organised with the support of the Department of Chemical, Materials and Industrial Production Engineering of the University of Naples Federico II.

All those with an interest in rheology, in all its aspects, are invited to submit contributions.

Selected papers will be eligible for a special issue in Rheologica Acta.
