Hi Paul,
Thank you for your reply. Yes, I have already examined the available documents and papers of the Physical Trough model since it is the model used for IPH Trough.
Nevertheless, while examining hourly results for thermal heat sink and mass flowrate at heat sink (which is eventually HTF mass flowrate in the boiler of the power block), I have noticed that mass flowrate deviates a lot from its design value, which can be calculated through an enthalpic balance: flowrate = heat_sink / ( (Tf-Tin)*Cp), I couldn't figure out the reasons for these deviations.
Regards,
