Version 4.0 (June 7, 2022)

ThermoSysPro modifications from version 3.2

• New package ThermoSysPro.Fluid

o   Package utilizes new fluid connectors that can handle all fluids in package ThermoSysPro.Properties.

o   Package handles thermal diffusion as a new option.

o   Package replaces packages ThermoSysPro.Combustion, ThermoSysPro.FlueGases, ThermoSysPro.MultiFluids, ThermoSysPro.WaterSolution and ThermoSysPro.WaterSteam.

• Component ThermoSysPro.WaterSteam.HeatExchangers.DynamicWaterWaterExchanger

o   Equation DPc[i] = p_Kc*ThermoSysPro.Functions.ThermoSquare(Qc[i], 1.e-3)/rhoc[i];  is replaced by  DPc[i] = p_Kc*Qc[i]^2/rhoc[i];

o   Equation DPf[i] = p_Kf*ThermoSysPro.Functions.ThermoSquare(Qf[i], 1.e-3)/rhof[i];  is replaced by  DPf[i] = p_Kf*Qf[i]^2/rhof[i];

• Component ThermoSysPro.WaterSteam.HeatExchangers.StaticWaterWaterExchanger

o   Equation DPc = p_Kc*ThermoSysPro.Functions.ThermoSquare(Qc, 1.e-3)/rhoc;  is replaced by  DPc = p_Kc*Qc^2/rhoc;

o   Equation DPf = p_Kf*ThermoSysPro.Functions.ThermoSquare(Qf, 1.e-3)/rhof;  is replaced by  DPf = p_Kf*Qf^2/rhof;

• Component ThermoSysPro.Fluid.Machines.Generator_11

o   Component is duplicated in package ThermoSysPro.ElectroMechanics.Machines for package Fluid

• Component ThermoSysPro.Thermal.HeatTransfer.HeatExchangerWall

o   New option: dynamic_energy_balance

• Package ThermoSysPro.Units

o   New package: SI that duplicates package Modelica.SIunits

o   New package: nonSI

o   New package: xSI

• All components in package ThermoSysPro

o   ThermoSysPro.Units.xSI.DifferentialTemperature is replaced by ThermoSysPro.Units.SI.TemperatureDifference

o   ThermoSysPro.Units.xSI.DifferentialPressure is replaced by ThermoSysPro.Units.SI.PressureDifference

o   ThermoSysPro.Units.xSI.MassFraction is replaced by ThermoSysPro.Units.SI.MassFraction

o   All references to Modelica.SIunits are replaced by references to ThermoSysPro.Units

• Component ThermoSysPro.Solar.Collectors.FresnelField

o   New parameter: Lc

o   New parameter: trackingFactor

o   New parameter: thermalLossPhy

o   Equation KL = cos(pi*thetaL/180)*(1 - h*tan(pi*thetaL/180)/L); is replaced by KL = cos(pi*thetaL/180)*(1 - h*tan(pi*thetaL/180)/Lc);

o   Equation dQloss[i] = pi*D*L/Ns*(0.5*F12*Emi*5.67e-8*(T[i]^4 - (0.0552*T0^(1.5))^4) + hc*(T[i] - T0)); is replaced by dQloss[i] = if thermalLossPhy then pi*D*L/Ns*(0.5*F12*Emi*5.67e-8*(T[i]^4 - (0.0552*T0^(1.5))^4) + hc*(T[i] - T0)) else L/Ns*(A1*deltaT[i] + A2*deltaT[i]^2);
