CET researchers awarded Solar Energy journal best paper 2021

Congratulations to mechanical engineering researchers Dr Matthew Emes, Dr Azadeh Jafari and Prof Maziar Arjomandi for receiving the Solar Energy Journal Best Paper Award 2021 from the International Solar Energy Society (ISES).

Solar award energy

Solar Energy journal best paper award winners Dr Matthew Emes, Dr Azadeh Jafari and Prof Maziar Arjomandi.

The biennial award was announced at the ISES Solar World Congress on Thursday 28 October (US Eastern time). The virtual event, which was held from 25-29 October 2021, connected the scientific and research community with renewable energy decision-makers, developers, financers, and practitioners to highlight key technology advances that are taking place in the field of solar and renewable energy.

Solar Energy, the official journal of the International Solar Energy Society, is devoted exclusively to the science and technology of solar energy applications.

The Society was founded in 1954 and is now incorporated as a non-profit educational and scientific institution.

With participation encompassing 100 countries, ISES serves as a centre for information on research and development in solar energy utilisation. Through its publications and its sponsorship of technical conferences, the Society provides a world forum for the active consideration of solar energy.

The paper investigated the aerodynamic wind loads on scale-model heliostats in the Thebarton wind tunnel to characterise the effects of atmospheric boundary layer (ABL) turbulence on the maximum wind loads on full-scale heliostats. A techno-economic sensitivity analysis of the design wind loads on different heliostat components indicated that their structural cost becomes increasingly sensitive to terrain roughness with increasing heliostat size. The results in the paper form a key component of Heliostat Wind Load Design Guidelines, developed as part of the SolarPACES Task III working group. The guidelines aim to provide a useful engineering tool for heliostat designers to estimate the loads on full-scale heliostats and reduce the cost of lighter structural components, based on the variation of ABL turbulence characteristics at different heliostat field sites.
