Bubble Sliding and Lift-off Analysis

Calculation of various bubble parameters during horizontal subcooled boiling flow

The image processing code for this package was written in cooperation with Amir Meghdadi. Image processing and data compilation package for analysis of bubble sliding and lift-off events. High speed greyscale videos of bubble nucleation, sliding, and lift-off events are required with either an in-frame scaling device or a known image scale. Individual bubbles are tracked from nucleation to lift-off and various parameters are measured, including sliding velocity, 3D equivalent spherical diameter, base diameter, maximum 3D diameter, lift-off 3D diameter, and (if resolution is high enough in the vicinity of the bubble base) contact angles and the angle of inclination. Parameters are measured in each frame for a particular bubble and are outputted as raw data in a Microsoft Excel file. After the user has analysed all useful bubbles, the data is compiled and summarized in a Microsoft Excel file.
