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.
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. Regular and abnormal combustion processes in ICE. Part load operation of SI and diesel engines. ICE performance curves. Supercharging and turbocharging: basic plants design, application fields, operational issues, thermodynamic cycles, compressor and turbine power. ICE pollutant emissions: 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.
