Void volume fraction of granular scaffolds

Small, 2022
AbstractVoid volume fraction (VVF) of granular biomaterials is a global measurement frequently used to characterize void space. There is currently no gold standard for measuring the VVF of granular scaffolds made in lab. To help the biomaterials field, we provide a library of different simulated scaffolds with known VVF for easy look-up.

Effect of void fraction on capacitance of sensor for void fraction measurement

European Journal of Mechanics - B/Fluids, 2021
Abstract Capacitance sensor is a non-intrusive devices used for the void fraction measurement in two-phase flows. Capacitance sensor is formed by two electrodes placed at the outside walls of a dielectric pipe, through which a two-phase medium flows. The capacitance of the sensor depends on the geometric arrangement of electrodes and distribution of ...

Void fraction dynamics in fluidization

AIP Conference Proceedings, 1992
A nonlinear evolution equation for void fraction in fluidization is derived from a one‐dimensional continuous model by applying the method of adiabatic eliminations. Based on our equation, the dynamics near the transitions point from stable fluidized beds to unstable ones is investigated. Phase separations in fluidized beds are also discussed.

Experiments on void fraction waves

International Journal of Multiphase Flow, 1989
Abstract Experiments on the propagation of small void fraction disturbances along an upward vertical test section are reported, for bubbly flows and transitional (bubbly-slug) flows. Wave attenuation and propagation speeds are discussed. In particular, it is shown that two propagation phenomena, with different speeds, may coexist, the higher speed ...
