MATLAB Code for Visualization of 3D Steady Micropolar Poiseuille Flow in a Plane Channel

This MATLAB script implements the exact analytical solution for three-dimensional steady micropolar Poiseuille flow between two infinite parallel plates under no-slip and no-spin boundary conditions. It generates six figures visualizing the velocity profiles, microrotation fields, and the influence of key parameters such as microrotational viscosity, microinertia coefficient, and the characteristic micropolar length scale. The code is designed for educational and research purposes, enabling verification of theoretical results and exploration of limiting cases including the Newtonian fluid limit.
