Seat Ingegneria
A.A. 2015/2016
Credits 9
Hours 72
Period I
Language ENG

Prerequisites
basic concepts of physics, thermodynamics and fluidynamics

Learning outcomes
The aim of the course is to provide the student with the tools for understanding the operation of the main energy conversion systems and of the fluid machines they contain.

Program
introduction and classification of energy conversion plants and fluid machines reminds on thermo- and fluid-dynamic concepts applied to fluid machines steam plants: thermodynamical cycles and methods to increase conversion efficiency; steam generator and basics on the other components of the plant: condenser, pump, turbine, surface and direc contact regenerative heat exchangers. turbogas plants: thermodynamical cycles and methods to increase their conversion efficiency and specific work. basics on turbogas plant components: compressor, combustion chamber and turbine. hydraulic energy exploitation in hydraulic plants – Pelton, Francis and Kaplan turbine types positive displacement pumps and centrifugal pumps. positive displacement compressors principals of reciprocating internal combustion engines: reference cycles for both compression and spark ignited engines, combustion process in internal combustion engines fuel injection plants; torque and power curves and load matching

Development of the examination
LEARNING EVALUATION METHODS
The assessment of student's learning will take place by means of an oral preceded by a written pre-test consisting of synthetic answers to three or four questions about basic topics. the overcoming of the pre-test is needed for the admission to the oral examination.

LEARNING EVALUATION CRITERIA
the assessment of learning, based on the results of both the written pre-test and the oral exam, consists in verifing: the student's knowledge on the basic concepts connected with the operation of the machines and the energy systems covered during the course, his competence on machine and energy systems configurations and operating conditions, his ability to solve simple numerical problems with correct use of units and order of magnitude.

LEARNING MEASUREMENT CRITERIA
the student knowledge is graded through the attribution of a final mark out of thirty. The passing score is 18/30, the highest score is 30/30, brilliant students may receive in addition a praise. The final evaluation results from the weighted average of t

FINAL MARK ALLOCATION CRITERIA
The outcome of the evaluation is positive if the student proves to have knowledge of all the basic subjects covered in the course. The highest score is achieved by demonstrating in-depth knowledge of the course contents. Praise is given to students who are particularlly brilliant in exposure and/or demonstrat particular mastery of the matters treated in the course, being able to analyze topics not explicitly covered or to treat standard topics in alternative ways.
