AIMS AND CONTENT AIMS AND LEARNING OUTCOMES The course objective is to provide the students the basic knowledge on the motion of fluids and tools for the design and verification of simple hydraulic plants. Morover more complex fluid problems will be adressed by using simplified models. TEACHING METHODS frontal lectures SYLLABUS/CONTENT Fundamentals: The Continuum assumption. Physical properties. Forces acting on a fluid. Pressure and stress in fluids. State equation. Nonflowing fluids: Stress in a fluid at rest. Integral and differential equations for a fluid at rest. Pressure distribution in a constant density fluid and in an ideal gas subject to gravity. Pressure forces on plane surfaces. Pressure forces on curved surfaces. Pressure variation across interfaces. Surface tension. Kinematics of fluids Eulerian and Lagrangian description of the flow. Material derivative. Velocity and acceleration. Transport Theorem. Fluid Dynamics Stress in a moving fluid. Mass conservation principle and its integral formulation. Momentum principle and its integral formulation. Integral formulation of the angular momentum law. Applications of the integral formulation of fluid flow (Force of a jet on a surface, Borda losses, forces of a Pelton blade). Ideal fluids and Bernoulli theorem with applications ( efflux through a hole in the side of a tank, stagnation pressure, Pitot tube) Quasi-unidirectional incompressible flow Characteristic quantities (averaged velocity, discharge, The Piezometric Head, Kinetic Head, Total Head). Continuity equation. Momentum equation. Steady uncompressible flow in circular ducts. Bernoulli Theorem. Flow measurements devices (Venturi meter, thin plate orifice, flow nozzle). Fundamentals on hydraulics networks. Dimensional Analysis, model testing and similitude Dimensional analysis and Pi theorem. Applications (drag and lift on a body moving in a fluid).Model testing and similitude Fundamentals on boundary layer RECOMMENDED READING/BIBLIOGRAPHY Teacher's lectures notes(in italian) Marchi – Rubatta: Meccanica dei fluidi: principi ed applicazioni idrauliche, UTET 1981 Ghetti: Idraulica Libreria Cortina.
