Startup Nebia is poised to transform the experience of taking a shower. While developing its innovative new showerhead, the company’s engineers made thermal improvements to ensure that a shower, using much less water than the average, would be warm and comforting.
Fluid flow modeling aids Italian university researchers in characterizing the effects of explosive eruptions on nearby buildings.
High-speed trains in Spain cross more than just the plain.
Cavitation is the formation of vapor bubbles within a liquid when flow dynamics cause the local static pressure to drop below the vapor pressure. The bubbles usually last a short time, collapsing when they encounter higher pressure. Cavitation can cause noise and vibration, structural wear and damage, leading to reduced performance. It is a common problem in pumps (especially centrifugal or positive displacement pumps), compressors, hydraulic turbines, propellers, fuel injectors and other fluid devices subjected to high variations in pressure..
A common difficulty in simulating complex fluid flow problems is that some geometries can not be well-represented using a single, contiguous mesh. In many cases, different geometrical features are best represented by different mesh types. Preparing this mesh can be time consuming and complicated. Additionally, the large, poorly structured meshes that result can take excessive time to solve and can result in reduced accuracy.
To manage heat removal for LED lights, DuPont engineers used ANSYS CFD simulation to accurately predict temperatures within their proprietary substrate – information that could not be gained without simulation. This information is employed in guidelines to develop reliable substrates for lighting manufacturers that require a broad range of configurations.
