Dataset Description

This dataset contains simulation data corresponding to the study presented in the paper titled:
"Self-sorting of bidisperse particles in evaporating sessile droplets"
Authors: Aman Kumar Jain, Fabian Denner, and Berend van Wachem

Dataset Structure

The dataset includes six folders, each representing a distinct simulation case (C1 through C6) from Stage 2 of the simulation study, as outlined in Table 3 of the paper.

• Cases C1 and C2: Simulate droplets with an initial contact angle of 60°.

• Cases C3 and C4: Simulate droplets with an initial contact angle of 90°.

• Cases C5 and C6: Correspond to additional conditions as specified in the publication.

In each pair of cases:

• Odd-numbered cases (C1, C3, C5) neglect Marangoni stresses.

• Even-numbered cases (C2, C4, C6) include Marangoni stresses.

The suffixes in the case folder names denote particle types:

• “_S”: Standard silica particles

• “_N”: Neutrally buoyant particles

Each case folder contains:

• Subdirectories:

  • Fields: Fluid field data (e.g., velocity, pressure)

  • DMs: Particle and domain-related metadata

  • Meshes: Computational mesh files

  • Particles: Lagrangian particle data

• Visualization files:

  • results.xmf: XMF wrapper for reading fluid data (velocity, pressure, liquid volume fraction α) in ParaView

  • results_DEM.xmf: XMF wrapper for particle data visualization (e.g., position, velocity)

• Particle position data:

  • Five CSV files representing particle positions at five distinct time instances.

Analysis Script

A Python script named ParticleCombined.py is included. This script processes the particle position CSV files from each case folder to compute particle surface density over time.
