This source code provides a numerical solution for fluid-particle two-phase flow problems using the stream function method. The implementation serves as a reliable computational tool for researchers studying fluid-particle interactions in flow around objects. The code employs the stream function approach, a well-established numerical method in fluid dynamics that transforms the governing equations into a single scalar equation for efficient computation. The implementation calculates both the fluid velocity field and particle trajectories in two-phase flow scenarios. Key computational aspects include: discretization of the governing equations using finite difference methods, iterative solution of the stream function equation, and particle tracking algorithms based on Lagrangian approaches. The code structure allows users to modify boundary conditions, particle properties, and flow parameters to adapt to various problem configurations. This comprehensive implementation is particularly valuable for researchers seeking to understand the fundamental mechanics of fluid-particle interactions. It demonstrates practical application of numerical methods in computational fluid dynamics, making it suitable both for research purposes and as an educational tool for learning advanced fluid mechanics and numerical computation techniques. The modular code design facilitates understanding of each computational step, from grid generation to result visualization.
