Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Real | coeEtaQ (from Generic) | Vector of coefficients used to calculate thermal efficiency of the engine. The independent variable x1 is the steady-state power output, x2 is the cooling water mass flow rate, x3 is the cooling water inlet temperature. From index 1 to 27, coefficients correspond to the following terms: constant, x1^2, x1, x2^2, x2, x3^2, x3, x1^2*x2^2, x1*x2, x1*x2^2, x1^2*x2, x1^2*x3^2, x1*x3, x1*x3^2, x1^2*x3, x2^2*x3^2, x2*x3, x2*x3^2, x2^2*x3, x1^2*x2^2*x3^2, x1^2*x2^2*x3, x1^2*x2*x3^2, x1*x2^2*x3^2, x1^2*x2*x3, x1*x2^2*x3, x1*x2*x3^2, x1*x2*x3 | |
| Real | coeEtaE (from Generic) | Vector of coefficients used to calculate electrical conversion efficiency of the engine. The independent variables and mapping of the coefficients to the polynomial terms are the same as for the thermal efficiency | |
| Boolean | compute_coolingWaterFlowRate (from Generic) | true | If true, then an empirical correlation is used to calculate cooling water mass flow rate based on internal control |
| Real | coeMasWat (from Generic) | Vector of coefficients used to calculate cooling water mass flow rate in case coolingWaterControl is true. The independent variable x1 is the steady-state power output, x2 is the cooling water mass flow rate. From index 1 to 6, coefficients correspond to the following terms: constant, x1, x1^2, x2, x2^2, x1*x2 | |
| Real | coeMasAir (from Generic) | Vector of coefficients used to calculate air mass flow rate. The independent variable x1 is the fuel mass flow rate. From index 1 to 3, coefficients correspond to the following terms: constant, x1, x1^2 | |
| Modelica.Units.SI.ThermalConductance | UAHex (from Generic) | Thermal conductance between the engine and cooling water | |
| Modelica.Units.SI.ThermalConductance | UALos (from Generic) | Thermal conductance between the engine and surroundings | |
| Modelica.Units.SI.HeatCapacity | capEng (from Generic) | Thermal capacitance of the engine control volume | |
| Modelica.Units.SI.HeatCapacity | capHeaRec (from Generic) | Thermal capacitance of heat recovery portion | |
| Boolean | warmUpByTimeDelay (from Generic) | true | If true, the plant will be in warm-up mode depending on the delay time, otherwise depending on engine temperature |
