Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

In this paper, a new method to analyse Lissajous figures is developed. The model takes stray capacitance into account, leading to a more accurate equivalent circuit to describe the conditions during a discharge event. Using this method, the external measured current and the relationship between the filament current and the external current can be determined. The model also allows for calculation of the relationship between reduced electric field and ozone efficiency. In this paper, an optimized efficiency of ~207 g/kWh was achieved, at ~123 Td. The relationship between external current and ozone efficiency was also determined by changing gas pressure and barrier thickness. It was found that with increasing barrier thickness and increasing pressure, the ozone efficiency increased, while the external current decreased. The highest ozone efficiency achieved was ~225 g/kWh.
