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