CFD analyses


Computational fluid dynamics (CFD) analysis is one of the most complex tasks in mechanical engineering. Physical experiment in fluid mechanics is cost and time consuming. We offer numerical CFD simulation which is a very good alternative to the experiments. Result of the CFD simulation is a flow field which can provide information about flow velocity, pressure distribution and/or temperature distribution. We can solve stationary as well as non-stationary problems. The resulting pressure and temperature distribution can be afterwards used as an input loading in subsequent structural analyses to evaluate stresses and deformations. We are also engaged in aeroacoustics and aeroelasticity calculations. Upon performed calculations we can propose modifications to improve design and requested parameters.


CFD analyses may include the following tasks:

-      Calculation of stationary and non-stationary flow distribution

-      Simulation of internal and external aerodynamics

-      Calculation of heat transfer between structure and fluid due to natural or forced convection (CHT simulation)

-      Assessment of hydraulic resistance characteristics of systems

-      Turbomachinery efficiency improvement by optimization of internal geometry

-      Modeling of fluid-structure interaction (one-way/two-way FSI)

-      Prediction of self-excited oscillation due to fluid flow (aeroelasticity)

-      Calculation of steam phase changes in turbomachinery

-      Calculation of acoustic noise generation due to flow

-      Modeling of acoustic waves propagation

-      Assessment of structure response due to acoustic excitation

-      Comparison of different designs (different concepts, manufacturing technologies, materials‚Ķ)   


Benefits:

- Time savings

  - We can help you to meet the schedule

  - Identification of potential issues during the design phase (elimination of operational problems and warranty claims)


- Cost savings

 - Elimination of necessity to build a prototype (product behavior can be tested using numerical models)

 - Lowering of operational failure risk and thus reduction of costs related to solving the failures


- Competitive advantages

 - High quality engineering analyses reduce the potential of products to fail (faulty product harms the reputation of the manufacturer)

 - Our technical report can help you to demonstrate to your customer compliance with the requirements on the product
