A Novel Bipolar DC Connection Strategy for Photovoltaic Power Plants With a 50% Reduction in DC Cabling Length

Energy Science &Engineering, EarlyView.
Bipolar configuration is a new topology in the direct current (DC) system of photovoltaic power plants, which is topologically analogous to the bipolar configuration utilised in High‐Voltage Direct Current power transmission systems. DC cable length and copper usage are reduced by 50% using a bipolar configuration.

Experimental Thermal Performance Investigation of Nontracking Multiple Parabolic Trough Collector With a Single Absorber

Energy Science &Engineering, EarlyView.
With a mass flow rate of 0.3 kg/min, a direct solar radiation of 770.25 W/m2, and a global solar radiation of 915.25 W/m2, the maximum outlet water temperature was 63.3°C, the maximum instantaneous efficiency was 51.78%, and the average heat gain was found between 69.81 and 206.88 W, depending on mass flow rate and direct solar radiation.

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.

Burning Lessons: The Failure to Learn From Major Fire Incidents

Fire and Materials, EarlyView.
ABSTRACT Major fire disasters continue to cause substantial loss of life, economic damage, and social disruption worldwide. Although investigations occur in most countries, lessons learned are often fragmented, published in incompatible formats, or not published at all.
