Investigation of micro- and nanosized particle erosion in a 90° pipe bend using a two-phase discrete phase model. [PDF]
ScientificWorldJournal, 2014 This paper addresses erosion prediction in 3-D, 90° elbow for two-phase (solid and liquid) turbulent flow with low volume fraction of copper. For a range of particle sizes from 10 nm to 100 microns and particle volume fractions from 0.00 to 0.04, the ...

Coupled discrete phase model and Eulerian wall film model for numerical simulation of respiratory droplet generation during coughing. [PDF]
Sci Rep, 2022 Computational fluid dynamics is widely used to simulate droplet-spreading behavior due to respiratory events. However, droplet generation inside the body, such as the number, mass, and particle size distribution, has not been quantitatively analyzed. The

Enhanced discrete phase model for multiphase flow simulation of blood flow with high shear stress. [PDF]
Sci Prog, 2021 Shear stress is often present in the blood flow within blood-contacting devices, which is the leading cause of hemolysis. However, the simulation method for blood flow with shear stress is still not perfect, especially the multiphase flow model and ...

Analysis of Erosion Minimization for a Slurry Pump Using Discrete Phase Model Simulations
Applied Sciences, 2022 A slurry pump is a device used to transport slurry, which is a mixture of solids and liquids. The slurry pump is subjected to physical erosion, generally resulting from erosion by friction between the solid and liquid particles.

Study of Dual-Stage PDC Bit Flow Field Based on Discrete Phase Model
Shiyou jixie, 2019 To address the interferes of the flowback drilling fluid from the pilot bit of the dual-stage PDC bit with the flow field of the reaming bit, a new dual-stage bit hydraulic structure is formed by adding the inter-stage nozzle on the flow distribution ...

Settling of Mesoplastics in an Open-Channel Flow
Energies, 2022 Pollution of water by plastic contaminants has received increasing attention, owing to its negative effects on ecosystems. Small plastic particles propagate in water and can travel long distances from the source of pollution.
