The course deals with the fundamentals of positive displacement and dynamic fluid machines in order to analyse their functional behaviour and evaluate the key performance aspects.
The aim of the course is to provide the student a basic knowledge of positive displacement and dynamic fluid machines with reference to their functional behaviour and performance characteristics.
At the end of the course the student should achieve a basic knowledge about the operation of positive displacement and dynamic fluid machines and be able to evaluate the main performance aspects.
It is required that the student has acquired sufficient knowledge of the basic aspects related to applied thermodynamics and fluid mechanics.
The course is organized in lectures and exercises.
Classification of fluid machines. The energy equation and the expression of work. Conversion efficiency in fluid machinery. Work exchange in the positive displacement fluid machines .
Historical overview and fields of application. Basic knowledge on ICE: classification, components and nomenclature, main operational parameters. Ideal and real operation of 2 and 4 stroke engines. Indicated diagrams, indicated and brake mean effective pressure, engine power correlations. Reference thermodynamic cycles for spark ignition (SI) and diesel engines. Combustion processes: general aspects, combustion in SI and diesel engines. Part load operation of SI and diesel engines. ICE performance curves. Supercharging and turbocharging: basic plants design, application fields, operational issues. ICE emissions: pollutants formation processes and their effect on health and environment, influence of combustion process and operational engine parameters on exhaust emissions, emission control systems and aftertreatment devices for SI and diesel engines.
Reciprocating displacement compressors: operating principle, constructive characteristics, ideal and real working cycle, flow rate control systems. Rotary displacement compressors: vane, lobe, liquid ring, screw compressors. Volumetric pumps: alternative and rotary machines, working principle, construction types. Characteristic curves. Fluid machine-circuit matching.
