Stream simulations

THERMO-GAS Heat Exchangers work optimally if the constant flow of gasses into the heat exchanger is guaranteed. In case of unfavourable assembly conditions, we have made tests and measurements so far in order to optimise stream conditions. Due to the increased requirements on the performance of heat exchangers as well as expanded application areas it has become necessary to achieve optimised results already in the planning phase.

This is done by means of a CAD-based simulation which enables the very exact predicition of stream conditions. The performance opportunities of our heat exchangers are used at the best as a result of appropriate installed equipement for flow duct.

We would be pleased to provide you with our knowledge also beyond the heat exchanger technology.

The precise project

In case of a plant for catalytic combustion, the connecting hood to the heat exchanger was significantly shortened due to the assembly of a THERMO-AWT 3-Way Stop valve. After this change, the calculated performance of the heat exchanger has not been achieved anymore.

The connecting hood has been equipped with guiding plates the design of which had been defined due to several simulations.
The flow conditions before the retrofit of the connecting hood are illustrated in figure left, the simulation after the retrofit is shown in figure below.

The figure to the right shows the optimised connecting hood with the simulation of the flow conditions. The evenly arranged colours show that the flow speed is less than 3 m/sec in all sectors. Furthermore, you can clearly see that the entire heat exchanger is constantly charged.

After the retrofit of the connecting hood, the heat exchanger achieves the calculated performance again.
