Biofilm Deformation Model Validation with Synthetic and Pseudomonas Aeruginosa Data

A viscoelastic phase field model predicts biofilm deformation under fluid flow with relative errors of 12.8% for synthetic biofilm and 22.2% for Pseudomonas aeruginosa biofilm. The model was developed by Mengfei Li at the University of Notre Dame and validated using shear rheometry and optical coherence tomography experiments. This dataset likely contains the mechanical parameters and geometric comparisons used to evaluate the model's accuracy.

Use Cases

• Validate viscoelastic constitutive models based on experimental rheometry data
• Simulate biofilm deformation under fluid flow using the described phase field model
• Compare computational geometry predictions with optical coherence tomography measurements
• Design engineering systems for biofilm control based on model predictions

Strengths

• Model validation shows a relative error of 12.8% for synthetic biofilm.
• Experimental validation includes two distinct biofilm types: synthetic alginate and Pseudomonas aeruginosa.
• The study provides specific mechanical parameters determined via shear rheometry.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect bias inherent to the specific experimental and modeling setup described.
