beregningsfluiddynamikk

beregningsflui is a term that translates from German to "computational fluid" or "calculation fluid." In the context of scientific and engineering simulations, it refers to the conceptual or simulated fluid that is used in computational fluid dynamics (CFD) calculations. This is not a physical substance but rather a mathematical model representing the behavior of a real fluid.

CFD is a branch of fluid mechanics that uses numerical analysis and algorithms to solve and analyze problems involving fluid flows. beregningsflui is the entity that these algorithms operate on. It's defined by a set of governing equations, such as the Navier-Stokes equations, which describe the conservation of mass, momentum, and energy for the fluid. These equations are discretized into a system of algebraic equations that can be solved by a computer.

The properties of the beregningsflui, such as its density, viscosity, and thermal conductivity, are defined based on the physical fluid being simulated. The simulation environment discretizes space into a grid or mesh, and the beregningsflui's properties and state variables (like velocity and pressure) are calculated at each point or cell within this mesh over time. The outcome of the beregningsflui simulation provides insights into fluid flow patterns, heat transfer, and other related phenomena, which are crucial for designing everything from aircraft and vehicles to medical devices.
