Numerical Simulation of a Millifluidic Magnetic Separation Chip

A simulation framework for a continuous, high-throughput millifluidic magnetic separation chip, implemented in COMSOL Multiphysics. The work by Zhenyang Xu, last updated in April 2026, analyzes how chip geometry, flow conditions, and magnetic configurations govern the separation of particles with continuous size distributions. Results demonstrate effective fractionation of particles over a 0–4 µm size range using a single magnet and finer separation within the 0–1 µm range using magnet arrays.

Use Cases

• Optimizing magnetic separation chip design based on simulated geometry and flow condition parameters.
• Analyzing particle fractionation efficiency based on simulated variations in magnet number and arrangement.
• Characterizing particle size distributions from separation outcomes using the provided visualization framework.
• Studying the effect of dynamic viscosity (temperature) on magnetic particle separation performance.

Strengths

• Simulation framework explicitly accounts for continuous and broad particle size distributions, a key challenge for realistic populations.
• Results demonstrate effective fractionation over a 0–4 µm range and finer separation within 0–1 µm.
• Framework couples multiple COMSOL modules (CFD, AC/DC, particle tracing) for systematic analysis.

Limitations

• Dataset scale is limited to 13.5 MB, containing primarily simulation outputs (MP4, DOCX) rather than raw numerical data.
• Row count and column-level documentation are absent; data structure must be inferred from the accompanying documents.
• The data is simulation-based; experimental validation is not included in this dataset.
