Attività/Activities

The scientific research activity mainly focuses on the following fields:

Local scour at hydraulic structures and energy dissipation phenomena

Physical and theoretical analysis of localized erosion processes:
a) at non-conventional (eco-friendly) transverse structures;
b) induced by jets (both on cohesive and non-cohesive beds);
c) at bridge piers.
Within these research areas, the Hydraulics research team has produced significant scientific results, contributing to the advancement of the relevant scientific literature.

Analysis of air entrainment processes in liquid flows

The analysis of flow aeration is essential for understanding flow dynamics at many hydraulic structures. Depending on the air content in the flow, hydraulic characteristics and the overall energy dissipation process may undergo significant changes. The study of these phenomena has important practical implications and is particularly relevant for the proper design of dam stepped spillways.

Phenomenological analysis of turbulence

Theoretical modeling of turbulence aimed at developing predictive models for erosion processes.

Water supply and sewer systems

Research activity has mainly focused on the analysis and optimization of specific issues related to these types of infrastructures.

Modeling of hydraulic structures

Physical models of dam spillways and other hydraulic structures have been developed and tested.
