kiirusväljad

Kiirusväljad, meaning "velocity fields" in Estonian, refers to the concept of a vector field where each point in space is assigned a vector representing velocity. This is a fundamental concept in physics and engineering, particularly in fluid dynamics and electromagnetism. In fluid dynamics, a velocity field describes the motion of a fluid at every point within it. The arrows of the field indicate both the direction and magnitude of the fluid's flow. For example, a swirling vortex would be represented by a velocity field where the vectors curve around a central point.

In other contexts, kiirusväljad can be used to model phenomena beyond fluid flow. For instance, in electromagnetism, one might consider the velocity field of charged particles. The mathematical representation of a velocity field is typically a function v(x, y, z) that returns a three-dimensional vector for each point (x, y, z) in space. Analyzing these fields allows scientists to understand and predict complex behaviors, such as turbulence in water or the propagation of waves. The study of kiirusväljad often involves differential equations to describe how these fields change over time and space.
