Computational methods in hydrodynamics

What is an example of computational fluid dynamics?
Turbomachinery CFD Simulation
Aircraft jet engines are a common example of turbomachinery, as they are gas turbines that produce thrust from exhaust gases.
CFD software is used extensively in the design and optimization of turbomachinery, from pre-processing, modelling, meshing, all through to post-processing..
What is the importance of computational fluid dynamics in aircraft design?
CFD is used to predict the drag, lift, noise, structural and thermal loads, combustion., etc., performance in aircraft systems and subsystems.
CFD is also a means by which the fundamental mechanics of fluids can be studied..
Why do we use computational fluid dynamics?
Computational fluid dynamics in particular allows engineers to test and improve designs of products where fluid flow, turbulence, and heat transfer are vital calculations..
Computational Fluid Dynamics (CFD) is the analysis of fluid flows using numerical solution methods.
Using CFD, you are able to analyze complex problems involving fluid-fluid, fluid-solid or fluid-gas interaction.

Subfield of fluid dynamics

In fluid dynamics, hydrodynamic stability is the field which analyses the stability and the onset of instability of fluid flows.
The study of hydrodynamic stability aims to find out if a given flow is stable or unstable, and if so, how these instabilities will cause the development of turbulence.
The foundations of hydrodynamic stability, both theoretical and experimental, were laid most notably by Helmholtz, Kelvin, Rayleigh and Reynolds during the nineteenth century.
These foundations have given many useful tools to study hydrodynamic stability.
These include Reynolds number, the Euler equations, and the Navier–Stokes equations.
When studying flow stability it is useful to understand more simplistic systems, e.g. incompressible and inviscid fluids which can then be developed further onto more complex flows.
Since the 1980s, more computational methods are being used to model and analyse the more complex flows.

Class of numerical methods in scientific computing

Particle methods is a widely used class of numerical algorithms in scientific computing.
Its application ranges from computational fluid dynamics (CFD) over molecular dynamics (MD) to discrete element methods.
