A flow field is a visual representation of the movement of fluids, such as air or water, in a specific area. It shows how the fluid flows, including its speed and direction, often using arrows or lines. Flow fields are important in various fields, including meteorology, oceanography, and engineering, as they help scientists and engineers understand fluid dynamics. In a flow field, each point in the area has a velocity vector that indicates the fluid's speed and direction at that location. This information can be used to predict patterns, such as wind currents or ocean currents, and is essential for designing structures like bridges and buildings to withstand environmental forces.
