BML
Born
from the experience of OMB (Officina
Marittima Bisognani, leader in the sector since 1926),
BML
avails of the most advanced calculation technologies
and avant-garde machinery for the achievement of models
and finished products for nautical propulsion systems.
Our collaboration enabled the validation of a threedimentional
finite element numerical methodology, by means of the
commercial software FloWorks, capable of evaluating
the pressure and speed distribution in the fluid dynamic
field and in particular on the blade surface.
By using computational fluid dynamics (CFD) it was
therefore possible to establish a method to forecast
the performance in different speed conditions of the
craft and propeller rotation, in terms of efficiency
relationship between the power given to the shaft and
the hydrodynamic impact. By understanding the threedimentional
field it was also possible to evaluate phenomenon of
cavitation, allowing the optimization of the project
and controlling the occurrence and the effect of such
phenomenon.
