Drag force correlations and effect of charged particles on drag force for particle-laden flows
, 2022 The Computational Fluid Dynamics (CFD) tool pafiX (particle flow simulation in explosion protection) focuses on modeling the electrostatic charging of particle-laden flows. In CFD simulations of two-phase flows, accurate drag force modeling is essential for predicting particle dynamics. However, since all existing drag correlations were established for

Advanced Science, EarlyView.Photobiomodulated microglia release engineered extracellular vesicles that deliver UFL1 to the injured spinal cord. UFL1 competitively binds p53 with MDM2, inhibiting p53 ubiquitination and stabilizing p53 signaling. This dual mechanism simultaneously promotes anti‐inflammatory microglial polarization and directs neural stem cell differentiation toward
