Automatic Adaptive and Targeted Localized Refinement in Transient Structural Dynamic Simulations Using the Multiresolution Finite Wavelet Domain Method

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT The multiresolution finite wavelet domain method has been meticulously studied in numerous wave propagation simulations, showing excellent convergence properties and very fast computing times. The multiresolution procedure always starts with the coarse solution, and then finer solutions can be superimposed on the coarse solution until ...

Detached Eddy Simulation (DES) of a Turbulent Premixed Flame Stabilized on a Bluff Body

Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 2, June 2025.
ABSTRACT As the demand for net‐zero emissions intensifies, low‐emission fuels (LEFs) are increasingly explored for their potential to reduce pollutants in combustion systems. The present study investigates the flame dynamics and pollutant emissions (CO and NOx) of different LEFs using detached eddy simulations (DES), a method that offers better ...

Adaptive Vibration Control of the Moving Cage in the 4 ×$\times$ 4 Hyperbolic PDE‐ODE Model of the Dual‐Cable Mining Elevator

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
This paper proposes an observer‐based adaptive output‐feedback boundary control to stabilize the vibrations of the moving cage of a dual‐cable mining elevator. This system is comprised of two mechanically jointed winding drums that drive the two cables through the floating sheaves to lift the cage.
