Scientific work

Our company has developed mathematical software (models and calculation programs) for studying the processes of air and gas flow in the section of the heat exchanger.

This allows you to design products in which the minimum aerodynamic resistance of the gas and air channels with the minimum weight and dimensions parameters.

As an example, the video shows the distribution of gas flows over the cross section of the heat exchanger (obtained from the design of the heat exchanger for a metallurgical plant).

It follows from the video that if not properly designed, the section of the heat exchanger is not fully used. This leads to an overestimated resistance of the corresponding channel, and in some cases, to the possibility of emergency situations.

The latter is possible, for example, if extreme gas channels allow hot gas to pass through, and extreme air channels do not let through (surfaces washed by hot gas are not cooled).

Such a visualization of the gas flow pattern makes it possible to eliminate design errors primarily for diffusers and convergers of heat exchangers.

Each recuperator is designed and manufactured according to the specifications of a specific client, which allows optimizing the dimensions, materials, weight and, accordingly, the cost of the recuperator.

Thermo Nord Stream LLC produces recuperators and other heat exchangers for various purposes.
