Aerodynamics
We conduct advanced flow analyses ranging from aircraft aerodynamics to gas dispersion modeling.
In aerodynamic simulations, air flow and equipment motion generate forces on the simulated structure. These forces and air flows are studied using CFD (Computational Fluid Dynamics) modeling.
Aerodynamic simulation can be utilized in diverse applications, from aircraft design to assessing wind loads on ships, modeling exhaust gas dispersion, and ensuring safe working conditions.
With our expertise, we can provide solutions for a wide range of challenging phenomena. Using our proprietary flow simulation software FINFLO, we can simulate the behavior of aircraft, such as fighter jets, under various conditions. Aerodynamic applications are challenging compared to many other applications because friction, or boundary layers, must be resolved with precision. This is why, in addition to commercial CFD software, we use our own software when work requires the highest level of accuracy.
Other application areas include simulating outdoor spaces on ships to ensure comfort, as well as modeling emissions, heat loads, and exhaust gas dispersion in industrial areas. Simulations provide information to support design and guide development work toward optimal solutions. Our aerodynamics specialists ensure high-quality and cost-effective project execution.
Using computational fluid dynamics, it is possible, for example, to determine the aerodynamic loads acting on an aircraft’s wings, stabilizers, and control surfaces. With these loads and a structural analysis program, the structural strength can be evaluated and service life predicted. The fluid dynamic solver and the structural analysis program can also be coupled to operate simultaneously, enabling the analysis of structural loads induced by time-dependent flow phenomena.

40 years of computational fluid dynamics: FINFLO supports the Finnish Air Force and European Space Agency
The FINFLO software is designed to simulate flows around aircraft, space probes and ships. Originating in the 1990s, the software remains relevant today, enabling advanced compressible flow calculations and simulations of dynamically changing flow environments.
Finding the full potential of CFD
CFD, or Computational Fluid Dynamics, is a method that is often utilized only for the post-design phase, although it is very well suited for wider and efficient use throughout the design process. Optimal use of CFD analysis generally shortens projects’ lead times and improves product assessment. It also provides an excellent basis for preparing digital twins. In process modeling tasks, CFD is an excellent tool for studying the components, for example.
Not only colorful pictures – CFD saves time and money
Did you know that by using computational fluid dynamics (CFD) you can save as much as 80 % in design time and 60 % in design costs? During the past 20 years, I’ve been lucky enough to participate in many interesting simulation projects both in Finland and abroad and have seen how clients have received instant help. But what is CFD really? Where can it be applied and why should it be utilized?
