Mixing Behavior of Natural Gas and Hydrogen in a High‐Efficiency Vane (HEV) Static Mixer

Energy Science &Engineering, EarlyView.
Static mixers play a crucial role in the safe transport of hydrogen‐blended natural gas. Computational fluid dynamics (CFD) was employed to investigate the effects of structural parameters of the HEV static mixer on the mixing behavior and homogeneity of natural gas and hydrogen. The modeling approach was well validated against experimental data.

Environmental Thermoeconomic Performance Analysis of Gas Steam Combined Cycle With Different Inlet Air Cooling Technologies

Energy Science &Engineering, EarlyView.
This study establishes an environmental thermoeconomic cost model to investigate the impact of two IAC technologies on the performance of a GSCC from three aspects of energy, economy, and environment. Under arid climate conditions, the SEC technology demonstrates superior performance in terms of cost‐effectiveness and environmental impact.

Experimental and Numerical Investigation of Cedar Façade Flame Spread With Respect to Sidewall

Fire and Materials, EarlyView.
ABSTRACT In response to growing energy conservation and carbon neutrality efforts, façade systems incorporating wooden materials have attracted increasing attention, which in turn raises concerns about their combustibility. This study presents a combined experimental and numerical investigation of flame spread along cedar façades.

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

Fire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.
