Wolf Flow by K.W. Jeter5/31/2023 ![]() ![]() ![]() The coefficient of static sliding friction was measured using the slip-stick method, and the static rolling friction was determined from measured shear on particles positioned between two hot-pressed plates. The impulse excitation technique was used to measure elastic and shear moduli, and compute Poisson’s ratio. Particle shape and size distributions were determined by coupling optical microscopy to an in-house image processing algorithm. Granular flow properties needed to drive numeric granular models were measured for improved numerical model predictions for Carbobead CP 50/140, 40/100, and 30/60 particles. Granular flows of sintered bauxite proppants were researched along an inclined plane for solar thermal energy storage applications. ![]()
