Our range of services

Reduction of flow-induced noise

With our help, you can effectively reduce the sound radiation of your products. We follow a structured approach based on scientific methodology and best-practice solutions:

  • Prediction by digital twin 

    We create a digital twin of your product to accurately predict the flow acoustics and gain insights into potential acoustic problems.

  • Development of simulation models

    We develop detailed simulation models to investigate the interactions between flows and acoustic phenomena. This enables us to carry out precise analyses and develop targeted solutions.

  • Optimization / Troubleshooting

    In the event of unexpected noises, we find the underlying causes and develop solutions. We work for you both in the development phase and on the finished (series) product. 

Measurement and simulation

Our answer for reliable decision-making

Since our foundation, we have pursued the concept of intelligently combining measurement and simulation. We verify CFD simulation results with real measurements on request. When we intelligently combine measurements and simulation in both directions, this creates additional added value for the validity of the results.

Realistic data for simulations

By measuring forces and vibrations, for example, we provide precise and realistic data that can serve as the basis for simulations.

Verification of simulation results

We use measurements to validate simulation results and test the accuracy of a method for the respective application. To do this, we first benchmark the results of a calculation against a comparable real measurement. This creates confidence for more demanding or complex issues that cannot be easily validated by measurement.

Time/cost efficiency

If an existing product can be measured, real measurement data for simulation models is not only more precise, but also more efficient to collect.

Numerical acoustics for turbocharger noise

Project report

As the noise sources in cars are continuously decreasing, other noise generators, such as flow noise in turbochargers, are coming to the fore. Novicos has developed a pragmatic modeling methodology for predicting the sound field using the example of a BorgWarner turbocharger.

We record the influencing factors across disciplines and create multi-physical concepts. For example, we regularly work on projects using measurement systems, flow simulation, flow acoustics and vibration analysis. With our team from the fields of acoustics, vibration, strength, flow, kinetics and electromagnetics, we are able to penetrate even the most unusual applications. We frequently work on projects involving a combination of flow simulation, aeroacoustics and vibration analysis.

Fluid-structure interaction

We are a service provider for fluid-structure interaction

Fluid-structure interaction (FSI) describes the interaction between solid structures and surrounding fluids, such as air or water, in which mutual influences arise. In technical applications, FSI phenomena are often decisive for the performance, reliability and longevity of systems, such as aircraft wings, bridges, wind turbines or underwater vehicles. 

Overall, the calculation of fluid-structure interaction requires a deep understanding of fluid and solid mechanics as well as numerical methods to solve complex coupled problems. Novicos is able to calculate FSI problems.

The calculation is a complex process involving several steps:

Flow simulation (CFD)

The flow around the solid structure is calculated using computational fluid dynamics (CFD). CFD is a numerical method for solving equations that describe the behavior of fluids under different conditions.

Structural analysis (FEA)

The fixed structure is analyzed using finite element analysis (FEA) to determine the stresses, deformations and vibrations that occur under the influence of forces, such as the flow forces acting on the structure.

Coupling of CFD and FEA 

The coupling between the two analyses (CFD and FEA) forms the core of the FSI calculation. The flow forces from the CFD analysis are transferred to the structure and taken into account as external loads in the FEA. At the same time, the deformations of the structure influence the surrounding flow, which in turn changes the flow forces. This reciprocal process is repeated until a state of equilibrium is reached and the solutions hardly change in successive iterations.

Software integration

Specialized software packages that integrate both CFD and FEA methods are used for FSI calculations. These software solutions enable efficient and precise analysis of fluid-structure interaction.

Methods

Our calculation expertise 

Based on the complexity of the problem, we use a wide variety of methods to predict the flow noise. For example, we use analytical methods, integral methods and fully discretized simulation models. Special solutions are often necessary for the most efficient calculation, which we provide by developing our own methods.

Research into flow acoustics and aeroacoustics

We develop new methods

As a science-oriented SME, we are involved in various research projects in aeroacoustics and flow acoustics. We enrich flow acoustics with the development of methods and the expansion of knowledge about physical relationships.
