Seton, Sarah J. (2024) Optimising Multimolecular Film Performance on Water Surfaces. [USQ Project]
Abstract
As evaporation represents the primary source of water loss in dams and reservoirs in Australia, it is critical to improve the efficacy of evaporation mitigation technologies (EMT’s) (Craig I 2005; Baillie 2008). Chemical suppressants such as monolayers and multimolecular films have been a key focus of evaporation mitigation research, however their adoption has been limited largely due to their highly variable efficiency (Schmidt et al. 2020; Abdallah et al. 2021; Barnes 2008). The primary aim of this research project was to investigate multimolecular film behaviour at variable doses, quantifying relationships between dose and spreading rate and an optimal dose recommendation. The secondary aim was to explore the potential to detect multimolecular films using remote sensing techniques.
The methodology utilised in this project was primarily drawn from existing research paper investigating the spreading and dispersive properties of monolayer. In these research papers the position of the leading edge was tracked and plotted against time to determine the spreading rate (Brink et al. 2017; Wandel et al. 2017).
Findings indicate a significant relationship between applied dose and the film behaviour, emphasising the importance of understanding the applied dose when trying to maintain the integrity of the multimolecular film. Improvements in the effective use of multimolecular films in practical applications may be achievable by applying a recommended dose of 0.60ml/m2 every 8 days. While the development of a film detection system was not successful, the study underscores the need for further research in this area.
