The Critical Role of Economies of Scale: A Techno‐Economic Assessment of Small‐ Versus Large‐Scale Biogas Upgrading in Rural Tanzania

open access: yesEnergy Science &Engineering, EarlyView.
Small‐scale biogas upgrading can improve methane quality but remains financially unattractive to individual rural households. Community‐scale implementation substantially lowers energy costs, demonstrating that economies of scale are critical to making purified biogas a viable clean‐cooking option in Tanzania.

Post‐Stimulation Hydraulic Response and Productivity Constraints of a Low‐Productivity Carbonate Geothermal Well in the Small Intramontane Basin, Beijing Piedmont, North China

open access: yesEnergy Science &Engineering, EarlyView.
Formed ~1.4 Ga, the carbonate reservoir of the Jixian System is a key geothermal reservoir in northern China. Differential basin–mountain evolution since the Cenozoic led to distinct reservoir‐forming histories; consequently, this same reservoir shows marked productivity contrasts between intramontane basins and the large rift Bohai Bay Basin ...

An Experimental Study of Thermal Energy Storage With Phase‐Change Material in a Rectangular Box Filled With Aluminum Foam

open access: yesEnergy Science &Engineering, EarlyView.
We experimentally evaluate a rectangular latent‐heat thermal energy storage box filled with paraffin RT57. Embedding 1–3 aluminum‐foam pieces (ε ≈ 0.89 and 10 PPI) increases effective thermal conductivity, making the temperature field more uniform and accelerating phase change.

On the Variability of Results for Cylinder Flow: A Systematic Analysis of Parameter Sensitivity Within the Lattice Boltzmann Method

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
This study systematically investigates the variability of cylinder flow results. We provide a comprehensive overview of literature values and, using the lattice Boltzmann method (LBM), show that insufficient convergence studies and variations in simulation parameters are a plausible cause for the significant spread in data.

Artificial structures for human‐machine interfaces with closed‐loop interaction

open access: yesFlexMat, EarlyView.
Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...
