CFD stands for Computational Fluid Dynamics. Computational Fluid Dynamics is a branch of fluid mechanics and analyses fluid dynamics and studies the impacts and interactions of the surrounding environment. Fluid dynamics are numerical flow simulations and also used in the fields of thermodynamics, heat and material transfer, thermal expansion in materials, chemical reactions and more.
Flows and related phenomena can be described in differential equations. These differential equations cannot be fully solved by analysis - apart from a few special cases. In order to obtain technically usable flow solutions, these differential equations must be solved approximately: with the help of numerical calculation methods on a three-dimensional calculation grid, but only if advanced and refined structural models are developed in a way that it correctly evaluates the stiffness matrix of the structures under investigation, and if the correct thermal load can be detected.
Optimization of rotor blades
Numerous CFD simulations and structure analyses are necessary to cover a large range of parameters, as given for the optimization process of rotor blades. Starting from the CAD system to build the geometry, the analysis will end up in a fundamental database that can easily understand and optimize the helicopters. The needed higher computational resources, for example, HPC or Cloud Computing, the user can run the jobs on the Cloud Broker platform to solve the simulations in the cloud in the most sustainable way.
