UNH-RVAT Reynolds number dependence experiment

This repository contains the processing and plotting code, as well as the derived dataset from the UNH-RVAT Reynolds number dependence experiment performed in Spring 2014.

Reproducing these results

You will need Calkit and its dependencies installed in order to run the pipeline that generates all of the figures. You will also need to have a token set in your config to be able to pull the raw data (necessary for one figure.)

Clone this repository with:

calkit clone https://github.com/UNH-CORE/RVAT-Re-dep.git

After that, call calkit run.

Reusing these materials

The statistical data can be read from the CSVs in the Data/Processed directory. Each file in there is named according to which "section" of the experiment it corresponds to (performance or wake measurements,) and the tow speed at which it was performed.

If you'd like to reuse some of the data loading and plotting functionality in other Python code outside this project, add it as a Git submodule in your own repo with:

git submodule add https://github.com/UNH-CORE/RVAT-Re-dep rvat-re-dep

then install the Python package in local mode with:

pip install -e ./rvat-re-dep

You'll then be able to run code like:

import pyrvatrd

perf_curve = pyrvatrd.load_perf_curve(tow_speed=1.0)
perf_curve.plotcp()

See notebook.ipynb for more examples. Also see this repo for an example of how this data can be reused in your own project.
