COMPUTATIONAL FLUID DYNAMICS 2

WHAT IS CFD?


Many problems in product development are directly related to the flow of fluids, such as liquids or gases. This is because either the product design has a direct influence on the flow behaviour or these fluids are interacting with the product. To study the behaviour of moving fluids, the Code engineers perform analyses using Computational Fluid Dynamics (CFD). CFD is an advanced simulation technique in the branch of fluid mechanics that uses numerical methods to solve and analyse fluid flows.
 

HOW IT WORKS


Based on a CAD drawing of parts or assemblies, a computer model can be built up, very similarly to the well-known method of Finite Element Analyses. CFD analyses can be performed on either compressible or incompressible fluids regarding laminar or turbulent flows. Compared to analytical solutions which are limited to simple geometries,

 

CFD can be applied to arbitrary complex structures. On those, the interaction between fluids and surfaces with applied boundary conditions can be studied effectively by applying CFD.
 

WHEN DO WE USE CFD?

 
At Code Product Solutions, CFD analyses are frequently used when the case is related to the flow of liquids or gases. Like structural mechanical analyses, advanced CFD assessments are a fixed part of our CAE-driven design approach. Within the development process of products or parts, CFD analyses are the preferred simulation tool to investigate components ducting air or liquid flows to either optimise the flow or various properties of the component. This can reduce the number of experimental tests and different hardware prototypes significantly, saving time.

Virtual Flow

CFD analyses allow the assessment of multiple aspects related to fluid flows, such as the determination of pressure loss, velocity distributions, mass flows, flow forces, particle movements, or convective heat transfer. Our CFD experts have considerable expertise in building up CFD models representing the problems of our customers. By interpreting the results of these analyzes, they draw the right conclusions, which significantly contribute to the optimisation of a product or component. Additionally, CFD analyses can bring valuable insights to the flow conditions in cases where measurements are impossible or too expensive to carry out.

Fluid Structure Interaction

Fluid Structure Interaction (FSI) describes the interaction of movable and/or deformable structures with internal or surrounding fluids. Since structures and fluids are interacting and affecting each other, the solution must be derived from a coupled problem. FSI is frequently used in development projects of moving structures interacting with fluids, such as rotating fans or pumps.

Realistic Boundary Conditions

In some development projects we use CFD analyses to determine realistic loads or boundary conditions to be used in other kind of assessment like structural simulations. This can improve the accuracy of the predictive engineering significantly. For that reason, the CFD experts at Code work together with our other CAE-experts in interdisciplinary teams. This results in a very efficient, result-orientated way of modelling by ensuring highest quality of the simulation results.

THE BENEFITS OF CFD

  • Modelling of complex structures
  • Studying interaction between structures and fluids
  • Gaining deeper knowledge of the product
  • Better insight into critical flow parameters
  • More efficient alternative to measurements
  • Fewer hardware prototypes needed
