Understanding Computational Fluid Dynamics:

🔍 Computational Fluid Dynamics (CFD) is a branch of fluid mechanics that utilizes numerical methods and algorithms to solve and analyze fluid flow problems. It involves discretizing the fluid domain into smaller computational cells and solving the governing equations to predict flow behavior.

Key Components of CFD:

🖥️ Grid Generation: The first step in CFD involves creating a computational grid, or mesh, that discretizes the fluid domain into finite elements or control volumes. The quality and resolution of the mesh significantly impact the accuracy and efficiency of the simulation.

📊 Governing Equations: CFD relies on solving the fundamental equations of fluid flow, including the Navier-Stokes equations for conservation of mass, momentum, and energy. These partial differential equations describe the behavior of fluid flow and are solved numerically using iterative methods.

🔬 Boundary Conditions: Boundary conditions specify the flow properties (e.g., velocity, pressure, temperature) at the boundaries of the computational domain. They play a crucial role in defining the problem and determining the flow behavior within the domain.
