FLUID MECHANICS

The Fluid Mechanics is an important scientific field in modern science and engineering. Within the course the physical principles and the main engineering applications are presented. Starting with the basic concepts and definitions, then described the static fluid, the kinematics of fluids and fluid dynamics. Additionally, the kinematic equations of real fluids and the energy equation, the boundary layer theory and the theory of the thermal boundary layer, the turbulent flow and turbulence models are studied.

Objectives

At the end of this course the student should be able to 1. To know the physical properties of the fluids. 2. To know the types of fluids (Newtonian, non Newtonian, Ideal), as well the types of the flow (laminar, turbulent, steady, unsteady, rotational, irrotational, etc). 3. To be able to study the equilibrium of fluids. 4. To be able to study the movement of fluids. 5. To be able to study the dynamic of fluids. 6. To be able to apply the kinematics equations of fluids for the solution of the flow problems. 7. To be able to apply the dimensional analysis and similarity for the study of the flow fields. 8. To be able to define the physical problem, the mathematical problem and to select the suitable method for the solution, and after that to valuate and interpret the results. 9. To be able to apply the basic laws of Fluid Mechanics to meteorology, astrophysics, biomechanics, aerodynamics, new power energy, etc.
