I'm preparing the title of my PhD dissertation and have lost confidence in the use of my prepositions.
- The title is "A Study on the Near-Surface Flow and Acoustic Emissions of Trailing Edge Serrations"
- The subtitle is "for the purpose of noise reduction in wind turbine blades".
Suddenly that last "in" feels like it could be "of" (despite feeling it would lose some nicety in how it sounds).
What do you think is grammatically correct though?
