A study of Free Convection in A solar Chimney Model [PDF]

Engineering and Technology Journal, 2011
A solar chimney is a hot air channel attached to a circular translucent roof opens at the periphery. The roof and the ground below it form an air collector. It enhances natural ventilation by employing air temperature difference between channal inlet and

Urban and Power Plant NOx Emissions in Sub‐Saharan Africa Inferred From TROPOMI

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Nitrogen oxides (NOx) emissions are increasing rapidly in Sub‐Saharan Africa, affecting local air quality. Outside South Africa, most hotspots are relatively small, posing a challenge for traditional top‐down inversions. We tailor an existing top‐down wind rotation and Gaussian plume fit inversion to suit the relatively small NOx hotspots for ...

Solar Chimney Operation Variant

Energies
This paper presents a solar chimney that acts as a heat accumulator. It is based on its alternating charging (melting of the phase change material—PCM) and discharging (solidification), which helps to save energy and ensures stable operation of the solar chimney.

Downdraft Devices for Negative Emissions—Quantification Study and Environmental Implication

Greenhouse Gases: Science and Technology, Volume 16, Issue 1, Page 75-89, February 2026.
ABSTRACT Methane (CH4) is a potent greenhouse gas with a global warming potential far exceeding that of CO2 over short time horizons. Its removal from the atmosphere remains challenging due to its low ambient concentration and chemical stability. This study explores downdraft energy towers (DETs) as an innovative CH4 mitigation technology that enhances
