Optimising Wastewater Treatment Plants with CFD & Drift-Flux
In the UK water industry, regulatory asset management plan (AMP) cycles create a relentless drive for efficiency. Water utilities and their engineering partners must continuously maximise the performance of existing infrastructure and de-risk capital upgrades for new assets. This is especially critical in complex processes like activated sludge treatment, where operational performance directly impacts environmental […]

How CFD Can Help Meet Dam Safety Regulations
Although the probability of a dam failure is often low, the consequences of one can be catastrophic. In the US, since 1980, there have been on average 24 dam failures per year, with overtopping the most common cause. Overtopping is where excess river flow causes the water level to spill over the top of the […]
PUR Foaming Simulation with HELYX
Polyurethane or short PUR or even shorter PU is impossible to avoid in our modern life. Since its discovery in the late 1930’s in Leverkusen it has been used for countless purposes. In its foamed-up form it is insulating our houses and refrigerators, it lets us sleep soft and comfortable at night and is used […]
