00430 - Technical Physics

Learning outcomes

At the end of the course the student is able to model and solve problems on the following topics: energy analysis of thermodynamic systems, newtonian fluid flow within ducts under laminar and turbulent regimes, heat conduction in plane and cylindrical geometries, including internal heat generation, convection heat transfer, radiation heat transfer, in plane and cylindrical geometries.

Course contents

Notice: the English version of the course is sketchy because it will be held in Italian anyway, so the following is only aimed at giving a potential foreign student a general impression of the course prior to choosing whether to enlist for the Italian degree in 'Ingegneria Biomedica'. For further details, please e-mail the instructor.

Introduction: basics and definitions. The first law of thermodynamics for closed systems. Thermodynamic properties of pure substances. Control volumes and the first law. Second law of thermodynamics for closed systems. Entropy. Steam power cycles and vapor compression refrigeration cycles. Gas turbine cycles.  Fluid mechanics. Momentum and energy conservation equations.  Basics of heat transfer. Unsteady heat transfer. Conduction heat transfer. Convection heat transfer. Radiation heat transfer. Biothermal equation.

Teaching methods

Numerical examples where theoretical principles are applied; use of thermodynamic tables and charts to solve problems.

Assessment methods

Written test to access the oral part. The written test consists of three exercises on the three main parts of the program (Thernodynamics, Fluid Mechanics, Heat Transfer), with a maximum of 36 points; 18 points are needed to be allowed to the oral examination. The oral examination takes part next to the communication of the outcomes of the written tests  and consists of two questions on the subjects treated in the course. A wide selection of past written tests complete with their solution is available at: http://campus.unibo.it/
