3D-Printed Solar Cavity Receiver for Heating Pressurized Air – A Preliminary Evaluation

SolarPACES Conference Proceedings
High-temperature solar receivers experience non-uniform solar flux, which induces thermal stress in the receiver tubes. This stress is more pronounced in gas solar receivers due to the lower thermal conductivity of gases.
