Evaluation of heat transfer and performance measurements of the HX

The task 5.4 of work package 5 of the COMPASsCO2 project is focused on testing and validating the performance of a particles/sCO2 heat exchanger mock-up. The objective of this document is to present the test measurements and the performance analysis. First, the measurements and test results are shown followed by the description of the different parameters required to assess the performance of the heat exchanger including its uncertainties. Finally, the performance results of the heat exchanger are shown and discussed. Furthermore, results of the impacts test on protective materials (Task 5.2.3) are included and discussed in the Annex
