The outcomes revealed that the ribbed absorber tube and the concentric rod insert are the most optimum turbulators. In addition, the parabolic trough collector equipped with a combination of corrugated channel and obstacle has a much better hydrothermal performance than the collectors using each of these turbulators separately.
For these reasons the parabolic trough collector is made up of a number of single receiver pipes connected in series up to the total length that is usually between 25 m and 150 m The parabolic trough mirrors are supported by a metallic structure and fixed using four mounting pads that are glued on the back.
According to their obtained results, the trapezoidal porous inserts in the absorber tube of the solar trough receiver improved the Nusselt number up to 13.80% at a 6.41 kg/s mass flow rate with just 1.7 kPa penalty in pressure drop.
