We are excited to announce a new paper, written by Jan E. Marquardt, Bastian Eysel, Martin Sadric Cornelia Rauh and Mathias J. Krause on the damage to fruits during transportation.
Fruit preparations are used in various forms in the food industry. For example, they are used as an ingredient in dairy products such as yogurt with added fruit. The dispersed fruit pieces can be described as soft particles with viscoelastic material behavior. The continuous phase is represented by fluids with complex flow behavior depending on the formulation. Characterization has shown that the fluids exhibit a yield stress and pseudoplastic behavior, which can be described by the Herschel-Bulkley model. The analysis is performed numerically using the homogenized lattice Boltzmann method and validated by an experiment on industrial fruit preparations at pilot plant scale. The results show a strong dependence of the damage potential on the (local) Metzner-Reed Reynolds number.
