报告摘要：

This study introduces a phase-field model designed to simulate the interaction and aggregation of multicellular systems under flow conditions within a bounded spatial domain.

The model incorporates a multi-dimensional Lennard-Jones potential to account for shortrange repulsion and adhesive bonding between cells. To solve the governing equations while preserving energy law, a second-order accurate C1 finite element method is employed. The validity of the model is established through numerical tests, and experimental data from cell stretch tests is utilized for model calibration and validation. Additionally, the study

investigates the impact of varying adhesion properties in red blood cells. Overall, this work presents a thermodynamically consistent and computationally efficient framework for simulating cell‒cell and cell‒wall interactions under flow conditions. The work is collaborated with Dr. Lingyue Shen, Dr. Ping Lin, Dr. Zhiliang Xu, Dr. Yuzhe Qin and Dr. Huaxiong Huang.
