Energy and exergy performance comparison of spiral tube receiver with thinner and thicker tubes for a solar parabolic dish concentrator

Puntos clave

• Energy and exergy performance differ significantly between thinner and thicker spiral tubes.
• The thicker tubes produced up to 15% higher thermal efficiency in specific conditions.
• Observational analysis across various tube designs showed notable variations in heat transfer capabilities.
• Significance lies in optimizing solar concentrator design; broader implications for renewable energy systems.
