Corrosion — caused by the liquid itself or by ambient humidity — can build up over the years and lead to structural failures. Recognised for its expertise in numerical simulation, EOLIOS models the wave generated by a product leak and assists manufacturers in sizing the retention devices, by determining the overspilled liquid quantity and the spread area.
Modelling the wave effects of a leak
When a leak occurs, a wave is generated and propagates through the liquid; it can have a significant impact on the retention devices. EOLIOS precisely models its propagation, taking into account the properties of the liquid and the tank. The model determines the overspilled liquid quantity, crucial information for correctly sizing retention basins and bund walls — an excessive overspill leading to environmental pollution and health and safety risks.
The simulation incorporates several parameters — gravity, liquid density, pressure, tank size, terrain topography and the presence of obstacles — fed into equations solved numerically to obtain a precise representation of the flow.
Spread area & sizing of the retention systems
Visualising the spread area
Beyond the overspilled quantity, our simulation visualises the extent of the contaminated zone: essential to assess the potential damage and the response measures. This representation helps to identify the at-risk zones and take preventive measures to minimise the consequences of a leak.
Sizing the retention devices
A critical design step: a prolonged overspill causes costly material and environmental damage. By simulating the flow — leak rate, fall height, distance travelled — we precisely determine the quantity of liquid outside the tank, making it possible to size the retention basins optimally.
Optimising the safety of industrial installations
Proper management of storage risks is essential to prevent accidents and spills, and an appropriate design of the retention devices is the key. From the wave modelling, EOLIOS recommends the ideal spread area by incorporating liquid viscosity, leak rate, tank geometry and environmental constraints.
Each case is unique and requires a tailor-made approach: our fluid-mechanics experts develop bespoke solutions that strengthen the safety of installations, reduce the risk of uncontrolled spillage and minimise the consequences for the environment and the health of workers.
