Furthermore, the creep-fatigue analysis displayed the damage accumulation due to cycling and the permanent deformation on the tubes showed that the tubes can operate for the full lifetime of the receiver.Energy Sources, Part A: Recovery, Utilization, and The structural integrity of the receiver was examined and it was found that the stresses can be withstood by specific tubes, determined by a parametric geometric analysis. A cyclic loading analysis is performed by coupling the Strain-Life approach and the Larson-Miller creep model. The lifetime performance of the receiver tubes were approximated using the resulting body stresses. Moreover, temperature and pressure distribution obtained from the thermal-fluid modeling (presented in a complementary publication) are used to evaluate the thermal and moreВ В» mechanical stresses along with detailed creep-fatigue analysis of the tubes. In this work, extensive candidate materials are review along with tube size optimization using the ASME Boiler and Pressure Vessel Code. Development of a solar receiver capable of delivering sCO 2 at 20 MPa and 700 вЊ is required for implementation of the high efficiency (~50%) solar powered sCO 2 Brayton cycle. В«В lessДЄ supercritical carbon dioxide (sCO 2) Brayton cycle is an emerging high energy-density cycle undergoing extensive research due to the appealing thermo-physical properties of sCO 2 and single phase operation. Finally, a receiver thermal efficiency ~85% was predicted and the surface temperatures were observed to be within the allowable limit for the materials under consideration. Understanding the effects of variation in heliostat aiming strategy and flow configurations on the thermal performance of the receiver was achieved through parametric analyses. CFD modeling is performed using ANSYS Fluent to predict the thermal performance of the receiver by evaluating radiation and convection heat loss mechanisms.

Moreover, an in-house MATLAB code is developed to couple SolTrace and ANSYS Fluent. Ray tracing, using SolTrace, is performed to determine the heat flux profiles on the receiver moreВ В» and computational fluid dynamics (CFD) determines the thermal performance of the receiver under the specified heating conditions. A coupled optical and thermal-fluid modeling effort for a tubular receiver is undertaken to evaluate the direct tubular s-CO 2 receiverвЂ™s thermal performance when exposed to a concentrated solar power input of ~0.3вЂ“0.5 MW. The development of a solar receiver capable of delivering s-CO 2 at outlet temperatures ~973 K is required in order to merge CSP and s-CO 2 Brayton cycle technologies.

In single phase performance and appealing thermo-physical properties supercritical carbon dioxide (s-CO 2) make a good heat transfer fluid candidate for concentrating solar power (CSP) technologies.
