Coupled modeling of a directly heated tubular solar receiver for supercritical carbon dioxide Brayton cycle: Optical and thermal-fluid evaluation

Ortega, Jesus ; Khivsara, Sagar ; Christian, Joshua ; ... - Applied Thermal Engineering

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. 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. A coupled optical and thermal-fluid modeling effort for a tubular receiver is undertaken to evaluate the direct tubular s-CO ₂ receiver’s thermal performance when exposed to a concentrated solar power input of ~0.3–0.5 MW. Ray tracing, using SolTrace, is performed to determine the heat fluxmore »« less

Coupled modeling of a directly heated tubular solar receiver for supercritical carbon dioxide Brayton cycle: Structural and creep-fatigue evaluation

Ortega, Jesus ; Khivsara, Sagar ; Christian, Joshua ; ... - Applied Thermal Engineering

A 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. Development of a solar receiver capable of delivering sCO ₂ at 20 MPa and 700 °C is required for implementation of the high efficiency (~50%) solar powered sCO ₂ Brayton cycle. In this work, extensive candidate materials are review along with tube size optimization using the ASME Boiler and Pressure Vessel Code. Moreover, temperature and pressure distribution obtained from the thermal-fluid modeling (presented in a complementary publication) are used tomore »« less
