Proc. ASME. POWER2020, ASME 2020 Power Conference, V001T01A002, August 4–5, 2020
Paper No: POWER2020-16443
...Abstract Abstract In heat exchangers, twisted tape insert is a technique to enhance heat transfer. In this paper, the experimental investigation is arranged to analyse thermal performance and entropy generation analysis on fluid flow in helical screw inserts with number of strips. The Nusselt...

... geometry with a constant aperture and a constant height. The comparison is made in terms of the absorbed radiation flux in the absorber tube and the entropy generation rate in a global and local way considering an LFR with 25 mirrors. The entropy generation rate considers the phenomena of viscous...

... and temperatures of the system. To calculate the second law efficiency, the entropy generation of all components of the combined cycle has been parametrically calculated. Furthermore, the optimal pressure ratio and working temperature for both cycles are represented. The influence of pressure loss in pipeline...
