“…Furthermore, as receiver tubes collect more solar irradiation from the collector facing side, the latter tends to reach higher temperatures. Thus, a low heat transfer coefficient results in a non-uniform thermal expansion of the receiver tubes, leading to an undesirable bending and possibly even breaking the protective glass cover [14,15].…”

“…The non-uniform heat flux distribution on the absorber outer surface increases the circumferential temperature difference on the absorber. This leads to the formation of bending stresses and damage to the vacuumed glass cover [23,24]. With the following equation, the maximum circumferential temperature difference ratios (Γ) on the absorber were determined.…”

“…The model was expanded in Khanna et al (2014) to obtain deflection and stress in absorber tubes supported at multiple points. This analytical model was also compared with experimental results (Khanna et al, 2016) obtaining a good correlation between them.…”
