A simple and novel coupling method for CFD-DEM modeling with uniform kernel-based approximation

The Eulerian-Lagrangian approach is commonly employed in particulate flows, which can be classified into two subcategories: unresolved computational fluid dynamics-discrete element method (CFD-DEM) and resolved CFD-DEM.

Research of Adsorption Experiments and Coupled Simulation of Multi-scale Flexible Tea Leaves

HortScience
To develop a new type of air suction sorting equipment for tea, we performed a bench test using a high-speed camera for test shooting and data analysis and established a computational fluid dynamics–discrete element method (CFD-DEM) coupling model.

Matrix Stiffness Orchestrates Mesenchymal Stem Cell Lineage Commitment Toward Osteogenesis and Adipogenesis Through the PIEZO1/SP1/STC2 Axis

Advanced Science, EarlyView.
Matrix stiffness directs mesenchymal stem cell lineage commitment through PIEZO1‐dependent activation of the SP1/STC2 pathway. Stiff matrices favor osteogenesis and suppress adipogenesis, whereas the loss of PIEZO1 function impairs early bone formation. STC2 retains lineage‐regulatory activity even when PIEZO1 is inactive.
