Riassunto analitico
This thesis proposes a study about Waste Heat Recovery for vehicle application through an Organic Rankine Cycle (ORC) which allows for the conversion of a diesel engine’s flue gas heat into mechanical power.
The thermodynamic cycle is optimized in the design point in order to obtain the maximum ORC system mechanical power with a particular fluid and thermal source temperature.
The heat exchangers are designed, the global heat transfer coefficients and the total heat transfer areas required by the thermal power flows are determined.
The data obtained are used as inputs in a model of the system (Vehicle + ORC) realized in Modelica language in order to simulate the off-design operation.
Eventually, an economic analysis allows to evaluate the fuel saving in relation to the initial investment costs and the feasibility of the system.
