Fundamental Principles of CFD
CFD relies on the Navier-Stokes equations, which describe the motion of fluids. These equations are fundamental to understanding and predicting fluid behaviour. Solving these equations numerically is the core of CFD.
The Navier-Stokes equations, in their most general form, are a set of coupled non-linear partial differential equations. These equations describe the conservation of mass, momentum, and energy within a fluid.
CFD Simulation Techniques
Various techniques are used to solve the Navier-Stokes equations numerically. These methods can be broadly categorised into different approaches.
- Finite Volume Method (FVM): This technique discretises the fluid domain into small control volumes. The governing equations are integrated over these volumes, leading to algebraic equations that are solved to obtain the solution. It is widely used for its relative ease of implementation and its suitability for complex geometries.
- Finite Element Method (FEM): This technique divides the fluid domain into smaller elements. The governing equations are approximated within each element, and the solutions are combined to obtain the overall solution. Its flexibility allows for complex geometries and non-uniform grids. It’s often used when modelling complex geometries.
- Finite Difference Method (FDM): This method uses discrete grid points to represent the fluid domain. The governing equations are approximated at these points, resulting in a system of algebraic equations. It is a simple method for structured grids and well-suited for simpler geometries.
Numerical Methods in CFD
Different numerical methods are employed to approximate solutions to the governing equations.
- Explicit Methods: These methods calculate the solution at a given point based solely on the solution at previous points in time. They are generally faster but may require smaller time steps for stability. It is less complex but may need more computational resources for accurate results.
- Implicit Methods: These methods involve solving a system of equations simultaneously at a given time step. They can handle larger time steps and are more stable but involve more computational effort. It is more complex but may offer higher accuracy and stability for complex flow simulations.
