Influence of Magnetron Sputtering Parameters on Speckle Characteristics for Application in Microscale DIC of Maraging Steel Open
Magnetron sputtering was utilised to deposit submicron-sized speckle patterns for microscale digital image correlation (DIC) of 18Ni-300 maraging steel. A Taguchi orthogonal array consisting of four configurations was used to investigate t…

Optimizing the piezocatalytic hydrogen production activity of metal-organic frameworks through precise defect engineering Open
The catalytic efficiency of metal-organic frameworks (MOFs) in piezocatalytic applications is currently greatly constrained by their limited piezoresponse. Herein, by using UiO-66 as an experimental platform, we show the feasibility of def…

An adaptive moving finite element method for steady low Mach number compressible combustion problems Open
This work surveys an r‐adaptive moving mesh finite element method for the numerical solution of premixed laminar flame problems. Since the model of chemically reacting flow involves many different modes with diverse length scales, the comp…

Evaluation of the unsteady flamelet progress variable approach in Large Eddy Simulations of the ECN Spray A Open
Within the Unsteady Flamelet Progress Variable – Large Eddy Simulation (UFPV-LES) approach the local scalar dissipation rate represents one key parameter, significantly affecting the ignition behaviour. In this study, the UFPV-LES approach…

Ignition Under Strained Conditions: A Comparison Between Instationary Counterflow and Non-premixed Flamelet Solutions Open
The transient evolution of counterflow diffusion flames can be described in physical space [i.e. by the model of Im et al. (Combust. Sci. Technol. 158:341–363, 2000)], and in composition space through flamelet equations. Both modeling appr…
