Sensitivity of Double‐Diffusive Mixed Convection in an Enclosure With a Zigzag Bottom Wall and a Torsionally Oscillating Lid Using Hybrid Nanofluid

Engineering Reports, Volume 8, Issue 7, July 2026.
This study investigates the nature of sensitivity of an unsteady double‐diffusive mixed convective analysis in a trapezoidal enclosure featuring a zigzag bottom wall and a torsionally oscillating lid. This cavity is filled by a hybrid nanofluid (Ag‐MgO‐H2O). The cavity also contains internal heat generation.

On the Non‐Dimensionalization and Mathematical Equivalence of MHD Nanofluid Jeffery–Hamel Flow

Engineering Reports, Volume 8, Issue 7, July 2026.
This study corrects inconsistencies in the governing equation and Hartmann number used in MHD nanofluid Jeffery–Hamel flow models. The corrected nanofluid formulation is shown to be equivalent to the classical MHD Jeffery–Hamel equation through appropriate parameter scaling.

Synergistic Enhancement of Solar Thermal Energy Storage Using Al2O3 Nano‐PCM and TiO2 Nanocoated Absorber Surfaces

Engineering Reports, Volume 8, Issue 7, July 2026.
Al2O3‐reinforced phase change material and TiO2 nanocoated absorbers enhanced solar heat absorption, thermal storage, and photothermal conversion efficiency. Optimized 1.5 wt.% Al2O3 improved thermal conductivity and energy retention, achieving 90.7°C outlet temperature and 79.5% thermal efficiency for advanced solar thermal energy storage applications.

A Comparison of Realized Measures of Integrated Volatility: Price Duration‐ vs. Return‐Based Approaches

Journal of Forecasting, Volume 45, Issue 4, Page 1579-1600, July 2026.
ABSTRACT We study the accuracy of a variety of parametric price duration‐based realized variance estimators constructed via various financial duration models and compare their forecasting performance with the performance of various nonparametric return‐based realized variance estimators.
