- •
The commercial parabolic collector IST-PTC is simulated with Solidworks.
- •
The developed model is validated by data taken from literature.
- •
The use of nanoparticles inside the thermal oil is investigated.
- •
The use of absorber with an internal wavy surface is examined.
- •
The final results show that the two ways increase the efficiency about 4.5%.
