Fluid Mechanics
Department of Fluid Mechanics
Fluid mechanics, a branch of physics, is fundamental to studying mechanical engineering, naval architecture, civil engineering and aeronautical engineering. The Department of Fluid Mechanics is focused on theoretical, experimental and computational approaches to fluid mechanics, including turbulent flow modelling and finding solutions for steady and unsteady flow of liquids and gases which involve heat exchange and phase change, in engineering, natural and biomedical sciences. In doing so, both the Department’s in-house software programs and commercial packages are used.

The Department is involved in teaching the fundamental programmes in
fluid mechanics for all specializations in the mechanical engineering and
aeronautical engineering courses. It also takes part iin teaching professional programmes of the specializations Process and Energy Engineering and Engineering Modelling and Computer Simulation, as one of the departments in charge.

It comprises two chairs dedicated to research and teaching. The Chair of
Computational Fluid Mechanics is involved in the application of fluid mechanics in:
  • analysis of steady and unsteady flow of liquids and gases in complex networks of piping (water piping, gas piping, oil piping, hot water systems...), including network sizing, analysis of their transfer capacities, pumping station design and hydraulic impact protection
  • cardiovascular circulation modelling (analysis of pressure and flow waveform propagation in large arteries) and application of computational fluid dynamics in the development of artificial heart pump
  • mathematical modelling and simulation of various problems related to fluid flow and heat exchange.
The Chair of Environmental and Structural Aerodynamics is engaged in
wind flow characterization in lower atmospheric layers, wind impact on
structures and vehicles, application of wind energy and other renewable
energy sources as well as gas expansion and particle dispersion in urban
areas. The research includes measurements done in nature, model testing done in wind tunnels and other types of laboratories as well as developing computational models. Besides the collaboration with other faculties and their departments within the University of Zagreb, e.g. the Daprtment of Geophysics at the Faculty of Natural Sciences and Mathematics, our Department also collaborates with eminent universities and research institutes internationally, including the following ones:
  • University of Florence, Italy
  • University of Notre Dame, USA
  • Institute for Theoretical and Applied Mechanics, Prague, Check Republic
  • Newcastle University, United Kingdom
  • Technical University in München, Germany
The state-of-the-art knowledge gained through research is directly introduced into teaching and it is applied in the real-life context.

  • Chair of Computational Fluid Mechanics
  • Chair of Environmental and Structural Aerodynamics
  • Hydrodynamics and Hydraulic Machinery Laboratory (a joint laboratory including the Department of Energy, Power and Environmental Engineering, The Chair of Turbomachinery and the Department of Fluid Mechanics)
  • Artificial Cardiovascular Circulation Laboratory
Dinstinctive features
The Department is the leader in the fields of computational and experimental fluid dynamics. As outstanding teachers and researchers, the Department’s staff have educated generations of experts in the field. Some of the projects carried out at the Department are: optimization of the Rijeka-Zagreb motorway wind barriers, simulation of electric arc quenching in high-voltage circuit breakers, simulation of continuous casting process, simulation of water system effect on electrical cables laid on parallel with these systems, simulation of exhaust gases flow at the gas turbine exhaust etc. The Department is dedicated to research and systematically seeks solutions to the problems related to environmental and structural aerodynamics, including road and rail vehicle safety and protection from cross-wind impact, optimization of the positioning and loading of wind turbines, buildings and other structures with complex geometry whose surroundings include complex topography, dispersion of harmful particles in urban surroundings, aerodynamic and aeroelestic loading of suspension and cable-stayed bridges along with their load-bearing stay cables.

The Department collaborates with industry and offers its clients support
in the development, improvement and optimization of the products that
involve fluid flow and heat exchange. It also offers its expertise and failure analysis assistance.

In addition, it conducts experimental testing of valves and hydraulic machinery in its laboratory and it offers expertise and computational simulations of complex piping network analysis, using the LIQNET and GASNET software which was developed at the Department.
