Information

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);
