Fluid flow
reducing ATEX level in engineof inland vessel by active ventilation.
The engine rooms of a LNG fueled inland vessel must suffice ATEX 1999/92/EG guidelines to ensure a safe working environment and prevent explosions. Furthermore, a lower ATEX level decreases the certification level of the ATEX Ex II 1g tools and equipment needed. That is why a design is made to lower the ATEX zone with active ventilation, requiring a lower certification for equipment and tools and improving the working environment.
improving engine rooms
active ventilation.
An active ventilation system is designed and analyzed using CFD tools. A simplified model of the engine room is made and meshed. Multiple simulations are conducted with varying circumstances. The flow and thermal distribution in the engine room is visualized and the ventilation requirements are checked.
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.
