Dataset for "Coating thickness prediction for a viscous film on a rough plate"

This dataset supports the publication 'Coating thickness prediction for a viscous film on a rough plate' by Lebo Molefe, Giuseppe A. Zampogna, John M. Kolinski, and François Gallaire, Journal of Fluid Mechanics, 2024. The data are film thicknesses measured for silicone oil films coated on rough plates. Please refer to the publication and its supplemental material for details.

Contents

Three folders containing the code and data required to produce the figures in the journal article and supplemental material.

Readme

A .txt file describing contents of code and datasets.

Code

Contains:

• Python code to produce Figures 5-10 and 12 in the main text, as well as supplementary Figures 1-4.
• Source code: COMSOL files for solving microscopic problem for effective parameters (L, Kitf) describing the rough surface; Python files for solving the macroscopic model equations once effective parameters are known.

Data

Contains data needed to plot the figures mentioned above, as well as supporting data.

The data includes density, surface tension, and viscosity measurements for silicone oil, with rheometry measurements performed on an Anton Paar MCR 302 rheometer, as detailed in the Supplementary Material.

Plots

Contains output of plotting code corresponding to the figures mentioned above.
