The flow of pharmaceutical pellets in a Wurster fluid bed (WFB) was characterized by a frequency domain analysis of pressure fluctuations. Pellets with a diameter of 0.780 mm and density of 1.225 kg/m3 were used in the experiments. Different flow str

The incorporation of a small amount of secondary immiscible liquid to suspensions can lead to a shift from a fluid-like structure to a paste-like structure. This is ascribed to the higher attraction of the secondary liquid to the particles, in compar

Objects are commonly moved within the cell by either passive diffusion or active directed transport. A third possibility is advection, in which objects within the cytoplasm are moved with the flow of the cytoplasm. Bulk movement of the cytoplasm, or

High-frequency seismic signals are generated during landslides and can be analyzed to obtain detailed information regarding landslide dynamics. However, a better understanding of the physical process that produces such high-frequency signals is requi

Traditional rotating drums are a popular type of tumbling mixer; however, they generally suffer from poor axial mixing with granular materials. To overcome this weakness, a system of alternately arranged baffles is presented, and its effect on partic

Fine particles play a significant role in many industrial processes. To study the dynamic behavior of fine particle and their deposition in rock fractures, the pneumatic conveying of fine particles (approximately 100 μm in diameter) through a small-

Joint interpretation of long- and short-period seismic signals generated by landslides sheds light on the dynamics of slope failure, providing constraints on landslide initiation and termination and on the main phases of acceleration and deceleration

Flexible filamentous particles are a special kind of particles and play a significant role in many industrial processes. The mixing dynamics of flexible filamentous particles in the transverse section of a rotary drum were analyzed numerically in two

Rotary drums, installed with longitudinal flights are often used to dry/cool granular materials in large quantities. Performance of such drums greatly depends on the uniform distribution of the particles over the drum cross section, which is attained
