We want to supply two turbines with one gas pipeline. It is important that both turbines are supplied with the same mass flow. Can you use a flow simulation to tell us whether the current design can do this and if not, what we have to do?

Project Objective:

Ensuring the uniform distribution in a pipeline branch for power plant turbines with the aid of a flow simulation.


Project manager, power plant construction


Our client manufactures special components (details confidential) in which coolant flows. Each component has one outlet and up to 20 outlets. The mass flow of the coolant is divided in the component according to the pressure loss. Ideally, the coolant must be distributed in such a way that all sub-sections are optimally cooled.

So far, the design has been based on the feeling and experience of the designers. Motto: “Somehow it was always possible. After the design, prototypes were built and tests were carried out. If it turned out that the cooling was not optimal, corrections were made and new tests were carried out until the result was acceptable.

This procedure is no longer up to date, and the client wanted software that would allow the designers to carry out a systematic design.


A Comsol Server App is optimal to combine the advantages of highly complex Multiphysics software with the advantages of individually created software.

We have created a pre-configured Comsol Server App for the client, with which he can achieve the required results with a few simple steps and little computing power.

The process is simple: the designer opens the app, selects the number of strands, defines the geometric parameters (e.g. line diameter and angle), specifies the mass flow and presses “Calculate”. The result is the pressure loss across all lines and the respective mass flow.

If he is not satisfied with the result, he can change parameters due to the existing boundary conditions, e.g. from production, and thus approach the desired result.

We would also be pleased to make this Comsol Server App available to you.
