Computational Fluid Dynamics (CFD) is a well-established and commonly used method for modelling fluid flow phenomena. The advantage of CFD compared with experiments or testing is its effortlessness and quick utilization.
Benefits of CFD
The most easily measurable advantages is reduced costs. The use of CFD can accelerate the design process and replace the use of expensive prototypes or similar systems.
In addition, it can be used in developing better products both in the design phase and in the upgrading of existing configurations. This results in cost-efficient and ecological products.
- Better functioning structures
- Reduces need for prototypes
- Cost-effective comparison of alternative designs
- Increased knowledge of flow phenomena
- Eases troubleshooting
Where can CFD be applied?
Everywhere. This means flows inside and around machines or devices as well as environmental flows. The flowing substance can be hot or cold, gas, liquid or mixtures of these. The flow can also be loaded with particles.
CFD is ideal for use in situations where a greater understanding regarding flow phenomena is required. A better understanding generates better products, which is of utmost importance in product development or in innovations.
Computational fluid dynamics, often referred to as CFD, is a science of predicting fluid flow and mass and heat transfer. CFD analysis can be performed to a device that might not exist yet. It can be used to understand phenomena, which are impossible or very difficult to measure. Inspecting results is not limited to a few points as in the measurements, where you need to decide the location of the sensors in advance, but can instead see inside the whole “black box”. Besides colorful pictures the results can be illustrated using plots and numerical data.
By thinking outside the box with the help of CFD you can test even wild ideas without building an extensive amount of prototypes. This brings you significant savings in both time and money. CFD analysis increases the knowledge on the device or process in question resulting in functioning, safe and ecological products. CFD should be an obvious choice in product development, concept studies, optimization, ergonomic studies, emission control, energy efficiency calculations, troubleshooting and customer care.
CFD analyses can be applied everywhere, from the flows inside or around devices to environmental flows. At Elomatic physical boundaries for a simulation can be defined using existing CAD models of the application in interest or drawn from scratch. This geometry is then divided into small discrete volumes i.e. meshed. Discretized partial equations describing the motion of fluid, heat and mass are then solved iteratively in these volumes. For solving and post processing Elomatic has several commercial, non-commercial and academic software to choose from.
