Validation of constant system performance

Assessment

Validation of system performance is done through direct

comparison between

measured sensor values in TES and numerically

simulated performance

● Virtually no difference in simulated versus

measured performance after operation for 1000 1500, 2000 and 2500 hours!

● TES, as whole, shows absolutely no sign of degradation
