Flow simulation

Flow simulation

Sizing on screen, before the first screw is turned.

With manufacturer-independent flow simulation, we size your agitator precisely to your substrate, tank, and process.

Our approach

Simulate first, then build.

We see on screen how substrate, tank geometry, and agitator interact long before the first component is manufactured.

The simulation shows flow patterns, dead zones, and mixing within the tank. On this basis, we select the agitator type, position, and power so that your agitator consumes less energy and reliably supports your process.

Patterns, velocities, dead zones
Mixing
Homogeneity throughout the entire tank
Energy
Power demand during ongoing operation

Simulation

What we make visible.

The simulation results form the basis for sizing. We coordinate with you to determine which evaluations are useful.

Your Benefits

What sets our simulation apart.

Four reasons why simulation before construction pays off.
Engineers analysing a flow simulation
Benefit 01
Manufacturer-independent, modern simulation software
We evaluate your plant objectively and independently of any specific agitator type.
Development of new agitator solutions as a team at Steverding
Benefit 02
Sizing precisely matched to substrate, tank, and process
We simulate substrate, tank geometry, and agitator in interaction before construction begins.

From Practice

Optimized flow, higher yield.

In a digester with a diameter of 28 m, we redesigned the mixing technology with a Spiralo®. After optimization, methane yield increased by 12%.
