a comparison of stairlift noise.

Liquid cooling systems run into the risk of cavitation when high flow speeds are required. This study shows experimental and numerical data on using inserts downstream of critical components, to successfully remove the cavitation risks. This is a great option when the downstream pressure cannot be controlled.

Quietly moving up and down

acoustic experiment.

We compared five stairlifts in this study: one from Koninklijke Otolift Trapliften and four from competitors. All stairlifts were performing a duty cycle during the measurements: starting in the lowest position, moving upward and subsequently moving downward. We used a manual scanning technique according to the ISO 9614-2 standard to determine the average intensity of each surface enclosing the stairlifts. The overall sound power level was subsequently calculated.

Demcon multiphysics.

Demcon multiphysics is an engineering agency with high-end expertise in the area of heat transfer, fluid dynamics, structural mechanics, acoustics, electromagnetism and nuclear physics. We support clients from a wide variety of market sectors and help them achieve their goals in research and development with deep physical insights.

We combine fundamental physical knowledge from an analytical approach with Computer Aided Engineering (CAE) simulations tools from ANSYS, MATHWORKS, COMSOL, STAR-CCM+ and FLUKA to setup, execute, analyze and evaluate numerical simulations. The use of Computational Fluid Dynamics (CFD), Finite Element Analysis (FEM / FEA), Lumped Element Modelling (LEM), Computational Electromagnetics (CEM) and Monte Carlo simulations enables us to make a virtual prototype of your design. With these techniques we can simulate the fluid and gas flows, energy exchange, heat and mass transfer, stresses, strains and vibrations in structures and the interaction of electromagnetic fields with other physical aspects like heat generation. Simulation-driven product development increases the development efficiency and reduces the product development time. Our services can therefore fully support you in the designing phase, from idea up to prototype, from prototype to final design.
