Luminosity and Pressure Data of the RDC

1. Overview

This repository contains raw and processed luminosity (HSV) and pressure data generated by M.D. Bohon et al. during RDC experiments. The luminosity data and pressure data describes different operating modes such as

• 2CR: two counter rotating waves traveling at same speed (ID: BD0041)

• 2CRT: two counter rotating waves traveling at different speed, where the faster one is larger in amplitude (ID: BD0038)

• DS2: one dominant wave and a set of two counter rotating traveling waves. (ID:CE2029)

3. Directory Details

data_input/00_hsv

• Contains raw high-speed video (HSV) luminosity data in .mat format.

• Filenames follow the convention:

  <ID>_HSV_CB076_<A####>_Phi<####>_<YYYYMMDD>_<START>_<END>.mat

  where:

  • <ID>: experiment identifier (e.g., BD0027, BJ0021).

  • <A####>: Surface Area of the injection holes (unsure).

  • Phi<####>: equivalence ratio.

  • <YYYYMMDD>: date of experiment.

  • <START>_<END>: defines a certain range within in the whole recording (unsure)

• Helper scripts:

• get_varname_hsv.m — extracts which of the variables in the workspace should be saved.

• load_data_hsv_input.m — loads raw HSV data according to the passed identifier (e.g. BJ0021).

data_input/01_pressure

• Contains raw pressure measurements in .mat format.

• Filenames follow the convention:

  <ID>_CB076_<A####>_Phi<####>_<YYYYMMDD>.mat

  where <ID>, <A####>, Phi<####>, and <YYYYMMDD> follow the same conventions as HSV data.

• Includes helper scripts:

  • get_varname_pressure.m — extracts which of the pressure variables in the work space should be saved .</p
