Optimization of an axial booster

At the request of one of our customers, with a view to modernizing the system, we analyzed and optimized the geometry of the ventilation ducts of a livestock vessel transport.
The project has been structured according to the following phases:
– Study of the characteristics of the existing ventilation system.
– Simplification of the 3D model and identification of a “typical” section of the ship.
– Creation of an FEM model for the fluid dynamic study.
– Iterative optimization of the geometry until the desired performance is achieved.

The basic requirement of a ventilation system for a livestock transport ship is the guarantee of a correct replacement of fresh air at every point of the ship’s bridges.
To achieve this result, it is often necessary to reach a compromise, during the design phase, between the performance of the various components of the ventilation system, such as:
– electric engines
– ventilation ducts
– suction and discharge openings
– fan blades

In this case the entire ventilation system was subject to modernization and therefore the pipelines had to be modified to reduce pressure losses and to improve the distribution of fresh air on each floor of the ship.

Starting from the pipelines present in a model section of the ship, we have created an FEM model of the plant. Going iteratively to modify the geometry of the pipelines we have arrived to obtain values of flow rate and air speed that guarantee a correct exchange in all the rooms of the ship.

All the technical documentation has been drawn up as indicated by the Machinery Directive.

The definitive accessory to which the CE matricular plate has been applied to SAECON has been realized.
