Hello everyone,
I am using evacuated collector type 71. Generally in literature, it has been written that evacuated tube collectors can`t reach temperatures higher than stagnation temperature which is 200 degree Celsius.
But in doing simulation, it is reaching temperatures higher than 200 degree Celsius.
I will appreciate if anyone could help me solve this doubt.
