modelEngineTemperature
Heat exchange within the engine control volume
Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).
Information
The model defines the dynamic behavior of the CHP thermal mass (i.e. engine block,
encapsulated working fluid, and internal heat exchange equipment) using a single,
engine control volume.
The thermal energy stored within this volume is quantified using an aggregate
thermal capacitance capEng and an equivalent average engine temperature
TEng.
The heat transfer between the engine and the cooling water control volume is
quantified using the overall thermal conductance UAHex,
while the heat loss to the surroundings is quantified using the overall thermal
conductance UALos.
