Optimized Mesh Zoning for Dam Bottom Outlet CFD Simulations Using Richardson Extrapolation and Grid Convergence Analysis

Engineering Reports, Volume 8, Issue 6, June 2026.
A Richardson‐extrapolation–based mesh zoning framework is developed to optimize CFD simulation accuracy and computational efficiency in dam bottom outlet flows. Using six mesh scenarios and multi‐parameter convergence analysis (pressure, velocity, TKE), the method identifies an optimal fine‐resolution zone around the gate and progressively coarser ...

La‐Tuned Scintillators With Nanosecond Response and High Flexibility for Blur‐Free X‐Ray Imaging

SmartMat, Volume 7, Issue 3, June 2026.
This work presents a zero‐dimensional Ce (III)‐based hybrid halide scintillator designed for real‐time and flexible X‐ray imaging. La3+ alloying synergistically enhances photoluminescence efficiency while preserving nanosecond‐scale decay. The resulting material exhibits a high light yield and low detection limit.

Ocean Wave Modulation of Offshore Wind Turbine Loads and Wake

Wind Energy, Volume 29, Issue 6, June 2026.
ABSTRACT This study examines how wave‐induced modulation affects the operational performance and structural dynamics of fixed‐bottom offshore wind turbines operating under a neutral atmospheric boundary layer profile. To capture these effects accurately while maintaining computational efficiency, unsteady RANS modelling techniques are employed.
