  "description": "<p>This paper presents the experimental evaluation of two volumetric solar absorber concepts. It compares the<br>\nthermal performance of conventional foam absorbers with that of an innovative rotary disc absorber design. The moving<br>\nabsorber showed advantages regarding air temperature stability at the outlet and better operability compared to the foam<br>\nabsorber. Unfortunately, it is shown that the innovative rotary disc design in its present form is not competitive, neither in<br>\nterms of thermal performance, nor regarding mechanical reliability and robustness. The future task is therefore to<br>\noptimize the mechanical design regarding thermal fatigue, in order to obtain a robust and durable rotary absorber that can<br>\nbe thoroughly evaluated experimentally.</p>",
