Glazing Effects on Dynamic‐Insulation TSC Façades: A CFD‐Supported Experimental Study of Flow, Heat Transfer, and Ventilation Preheating

Energy Science &Engineering, EarlyView.
Glazed transpired solar collectors achieve 48–75% efficiency and 11% more seasonal heat than unglazed designs by cutting convective losses, while both offer complementary benefits for ventilation preheating and dynamic wall insulation, with paybacks of 5.5–6.8 years.

Turbulence‐Intensity Effects on the Aerodynamic Performance of an H‐Type Darrieus Wind Turbine: A URANS Parametric Study

Energy Science &Engineering, EarlyView.
Turbulence intensity from 1% to 25% was parametrically tested on a three‐bladed H‐type Darrieus rotor across five tip speed ratios (TSRs) using two‐dimensional URANS. The optimal TSR proved the most efficient and most robust operating point simultaneously, with Cp losses capped at 5.8% even at TI = 25%. ABSTRACT The effect of inlet turbulence intensity
