This GitHub webpage hosts the Data and Code supporting the end-of-chapter sample exercises for the eBook by Ian Castro and Christina Vanderwel, Turbulent Flows: An Introduction, IOP, 2021.
The examples are also used in the module SESA6061 Turbulence at the University of Southampton.
Documented MATLAB codes are provided illustrating the solutions to each exercise; however, students are encouraged to try to solve the data analysis exercises on their own, before looking at the worked solutions. We hope to also provide solutions in other programming languagues such as Python in the near future. If you would like to contribute or suggest improvement, please contact the author at [email protected].
All code is shared under the MIT license and you can share and adapt it freely.
