ESTIMATION OF INTRINSIC VISCOSITY OF APPLE CELLS BY NUMERICAL SIMULATION
Résumé
A numerical simulation approach was proposed to estimate the intrinsic viscosity of particles with complex geometry. The approach is based upon the solution of the mass and the momentum conservation equations for an incompressible Newtonian fluid under steady-state creeping flow around the particle. The reliability of the approach is demonstrated after solving the problem for fluid flow around a small sphere, whose effect is known after theoretical work. The approach is then applied in solving the same problem for different apple cells. The intrinsic viscosity varies with the particle shape and its orientation, between 2.6 and 4.6.
