Numerical Investigation of Methane Transport Within and Around Evolving Cracks

Energy Science &Engineering, EarlyView.
A validated model shows that natural gas leakage induces soil deformation and forms three key cracks. When diffusion is low, methane moves mainly along the primary crack, demonstrating how natural fractures reshape pathways and significantly enhance methane migration.

Influence of Structural and Environmental Parameters on Solar Air Collector Performance

Energy Science &Engineering, EarlyView.
Increasing air gap depth and mass flow rate significantly enhances the thermal performance of solar air collectors, with optimal performance achieved at an 8.5 cm air gap and 0.01318 kg/s mass flow rate. Air gap depth is identified as the dominant factor influencing system efficiency.

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation

Fire and Materials, EarlyView.
ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.

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.

An Experimental Investigation on the Impact of Burner Height and Location on the Characteristics of Externally Venting Flames

Fire and Materials, EarlyView.
ABSTRACT Fire sources in actual compartment fires exhibit a predominantly uneven spatial distribution. In this context, the impact of the height and location of the fire source, as well as the heat release rate (HRR) of the fire, on the thermal characteristics of Externally Venting Flames (EVF) is experimentally investigated.
