Felsaris makes technical risks visible before time and budget are invested in prototypes, test benches, or test series. Pressure losses, overheating risks, unfavorable flow patterns, and system behavior can thus be assessed early and specifically improved.
Design decisions are often only validated after prototypes have been built. Each additional iteration incurs additional time and costs.
Pressure losses, overheating risks, unfavorable airflow patterns or other technical weaknesses are often only discovered when modifications have already become expensive.
Complex simulation projects require specialized CFD expertise and sufficient capacity, which is not always readily available in everyday development work.
Shorter development cycles and increasing competitive demands are increasing the pressure to secure technical decisions early on.
Without digital simulation, critical areas such as pressure losses, flow separation, temperature peaks or uneven flow patterns often remain hidden.
Test benches, test series and release processes are cost-intensive and tie up resources that are needed for the further development of new products.
Surface roughness in the turbine scroll caused fluctuating performance and efficiency losses. Using detailed measurements combined with validated CFD, we analyzed its impact on boundary layer behavior. The results highlighted critical regions and enabled targeted improvements, directly supporting supplier quality management.
Early prototypes failed under racing conditions, especially in the exhaust system. We delivered a complete redesign that combined lightweight construction with flow optimization. The result: higher durability and a clear performance boost.
Whether it’s flow simulation, thermal management, aerodynamics, engine development or virtual system simulation: Felsaris supports development projects from the initial concept evaluation to technical validation.
Dryer, kilns, valves, stirrer, tank filling/ sloshing, pressure loss reduction, vacuum cleaner, agricultural machines, electronics, etc.Diagnostic products in health care are explicitly excluded.
Project experience in automotive, motorsport, energy and mechanical engineering applications with high demands on performance, efficiency and reliability.
Flow, thermal management, aerodynamics and propulsion systems are analyzed as a coherent overall system in order to make interactions visible at an early stage.
From individual simulations and feasibility studies to long-term support of ongoing development projects.
