AN INVESTIGATION ON A SOLAR CHIMNEY MODEL [PDF]

Journal of Al-Azhar University Engineering Sector, 2019
A solar chimney system (SCS) is a solar thermal power plant utilizing a combination of solar aircollector and central updraft tube to generate a solar induced convective flow which drives pressurestaged turbines to generate electricity. In the present work, an experimental set-up model at themechanical engineering department of Al-Azhar University was ...

Solar Chimney Turbine Performance [PDF]

Journal of Solar Energy Engineering, 2003
An experimental investigation of the performance of a solar chimney turbine is presented. The design features a single rotor and uses the chimney supports as inlet guide vanes (IGVs) to introduce pre-whirl. This reduces the turbine exit kinetic energy at the diffuser inlet and assists the flow turning in the IGV-to-rotor duct.

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Multidimensional Energy Poverty, Food Expenditure, and Dietary Diversity Among Rural Households

Food and Energy Security, Volume 15, Issue 4, July/August 2026.
ABSTRACT This study examines the effects of multidimensional energy poverty on food expenditure, dietary diversity, and the consumption of key food groups among rural households in China. Using household survey data collected in 2023 from eastern, central, and western China, we construct a multidimensional energy poverty index and employ a conditional ...
