Technical devices and vehicles with gas, air or liquids flowing around or through them are ubiquitous nowadays: cars, vans and trucks as well as turbochargers, pumps, pipelines, vacuum cleaners or tumble dryers, etc. All devices have in common that their energy consumption directly depends on flow losses. The calculation of such flows, known as CFD (Computational Fluid Dynamics), is an indispensable tool for predicting the optimization of flow and heat transfer processes and is particularly essential when flow-related problems occur in the product.
The Problem: Unwanted Flow Losses / Pressure Losses
A flow loss or pressure loss occurs due to flow separations (recirculations) up to a complete stall. Flow separations are caused, among other things, by
- sharp deflections
- unsteady cross-sectional expansions
- component elements that are located in the flow path
Why are flow separations problematic?
Flow separation results in "bursting" of the jet. In addition to loss of pressure, another negative consequence can be noise generation. A CFD flow simulation reveals these unfavorable flow patterns and allows the targeted optimization of flow-conducting components.
The solution: Flow simulation / CFD
The calculation department of M.TEC is specialized in flow calculation by means of CFD (CFD = "Computational Fluid Dynamics") simulation. With extensive knowledge of the underlying physical relationships in fluid mechanics, we quickly deliver simulation results along with the correct interpretation. M.TEC develops flow-optimized concepts and derives appropriate measures from the results of the flow simulation - to optimize your component or product.
Flow simulation or CFD simulation is used to design and optimize flow-carrying components and flow-around bodies. Flow simulation computationally simulates flows and flow paths and visualizes the flow paths and flow paths of a flow.
As a service provider for flow simulation, M.TEC calculates different media with different viscosities (air, water, oils, gels, adhesives, etc.). Even the mixing of different media (e.g. an air/gasoline mixture or a multi-component adhesive) can be calculated with a CFD simulation.
Advantages of CFD
Computational fluid dynamics offers a cost-effective alternative to wind tunnel or water channel experiments for flow-related problems. For example, the number of test series can be drastically reduced. Therefore, flow simulation offers the right development tool for pressure loss optimization: It becomes clear where flow losses or pressure losses occur without extensive cost and time losses.
