Prerequisites: Basics of Mathematics and Physics
Target skills and knowledge: This undergraduate Fluid Mechanics course provides complete topical coverage on the basic aspects of incompressible fluid mechanics Topics covered include fluid statics, kinematics and dynamics. The latter considers specifically steady, one-dimensional pipe and open channel flow. The course is aimed at helping students to connect theory to the physical world through the solution and discussion of many practical problems
Examination methods: two written tests: the first includes two or three exercises, the second focuses on one of the theoretical topics of the course.
Assessment criteria: The evaluation of the student's preparation will focus on his understanding of the topics addressed, the acquisition of concepts and methodologies and on his ability in applying them in autonomy
Course unit contents: Introduction to Hydraulics.
Fluid Statics – The Hydrostatic equation. Fluid forces on straight and curved Surfaces. Buoyancy and stability.
Fluid Kinematics - Eulerian vs. Lagrangian approach. Flow velocity and acceleration (Cartesian and intrinsic reference system). Discharge. Shear velocity. Different forms of mass balance equation.
Fluid Dynamics – Inviscid flow: Euler and Bernoulli equations with examples (Pitot-tube, Venturimeter). Orifices and weirs. Momentum conservation equation with examples (Dynamic forces, propeller and turbine theory). Viscous flow: Navier-Stokes equations. Uniform laminar flow. The boundary layer: transition and instability (hints). Turbulent flow: the Reynolds averaged equations. Turbulent stresses. The turbulent boundary layer (hints). Smooth and rough wall. Loss of energy in pipes: the Darcy-Weisbach equation, the Gauckler-Strickler equation, the Colebrook-White friction factor. Minor energy losses (sudden enlargment). Systems of pipes. Pumps and turbines. Introduction to open channel flow: uniform flow, specific energy, Froude number, subcritical and supercritical flow, the hydraulic jump, gradually varying flow in open channels. Lateral inflow and outflow
