Pool Boiling Module

The functions are specific to data generated within our lab pool boiling setup. They are used to prepare data in the csv form required to training and testing

function PrepareHydrophone(…)

Parameters:

  • tempfilepath: path to labview generated temperature file

  • soundfilepath: path to labview generated hydrophone data file

  • savepath: path to save data

  • extracttime: boolean specifying whether to find the start time of the data from the labview files, do not use if start time in file is wrong (defaults to True)

  • tempstart: time in seconds of when the temperature readings started, not needed if extracting time (defaults to None)

  • soundstart: time in seconds of when the hydrophone readings started, not needed if extracting time (defaults to None)

Outputs:

  • Saves csv with time, hydrophone data, and heat flux

function PrepareAE(…)

Parameters:

  • aedata: path to saved AEWin summary data

  • aewaveforms: path to folder containing saved ae waveforms

  • tempfilepath: path to labview generated temperature file

  • output: path to folder where data should be saved

  • name: unique extension for the saved data corresponding to the experiment

  • extracttime: boolean specifying whether to find the start time from the files (defaults to True)

  • aestart: time in seconds of when the ae sensor starts reading, not needed if extracting time (defaults to None)

  • tempstart: time in seconds of when the temperature readings start, not needed if extracting time (defaults to None)

Outputs:

  • a csv file containing time and correpsonding heat flux and path to ae waveform txt files.

  • txt files with all ae waveforms

function PrepareImages(…)

Parameters:

  • imagepathfolder: path to location of folder containing images in .jpg format

  • tempfilepath: path to temperature file generated by labview

  • savepath: location to save csv data

  • framerate: amount of frames per second of camera

  • vidstart: time in seconds of when the video started

  • extracttime: boolean specifying whether to extract the start time from the temperature file

Outputs:

  • a csv file containing time, paths to images, and corresponding heat flux

function PreparePCAImages(…)

Parameters:

  • pcamodelpath: location to saved PCA model

  • imagecsvfile: path to csv file generated using the PrepareImages function

  • imgw: image width in pixels to resize image

  • imgh: image height in pixels to resize image

  • pcas: number of pcs the model converts images to

Outputs:

  • saves images converted to pcs to np file with the same name as the csv file
