Numerical Simulation of 2D Unsteady Micropolar Fluid Flow in a Lid-Driven Cavity with Full Dissipation Analysis

This dataset contains MATLAB source code for the numerical simulation of a two-dimensional unsteady micropolar fluid flow inside a square cavity with a moving top lid. The implementation solves the full Eringen equations using a projection method with upwind convection, computes the complete micropolar dissipation function, and generates comprehensive visualizations of velocity, microrotation, vorticity, pressure, and energy dissipation fields. The code is self-contained and requires only standard MATLAB functionality.

本数据集包含用于数值模拟带运动顶部盖板的方腔内二维非定常微极流体（micropolar fluid）流动的MATLAB源代码。该代码采用结合迎风格式对流的投影法求解完整的埃林根（Eringen）方程，计算完整的微极流体耗散函数，并生成速度场、微旋转场、涡量场、压力场及能量耗散场的全面可视化结果。该代码为自包含式程序，仅需标准MATLAB功能即可运行。
