We present a second law-based investigation on the heat transfer performance of paddle-shaft components. Entropy generation rate distribution is obtained through numerical simulation. show that design with hollow paddles (HP) transfers more and causes larger entropy than solid (SP). For HP, domain produces much less fluid material-solid interface. In domain, for SP, pressure drop-induced irreversibility negligible; it important when flow large. near holes, local largest, fluid-paddle...

Excessive thermal stress and deformation are important reasons causing disservice of high temperature heat exchangers. This paper presents expansion analysis single-leaf type hollow paddle-shaft components with internal molten salt flow based on three-dimensional numerical simulations. The results show that the paddles enhance transfer decrease maximum simultaneously expense a much higher pressure drop than solid paddles. cumulative von Mises distribution curve shows component is more...
Molten salt tanks are used to store and release thermal energy. Large heat leakage through the molten tank foundation ground high temperature of detrimental long-term operation safety. Here we evaluate transfer entropy generation characteristics foundations with internal water cooling. Both laminar turbulent flows reduce efficiently, while power consumption for flow is negligible. The effects geometrical parameters presented. Internal fins in cooling channels decrease significantly. total...
The ground heat exchanger (GHE) is a critical component of ground-coupled pump (GCHP) system, and its transient transfer performance significantly affects the overall system. Cost reduction through selecting promising GHE offers potential for increased applications. This study performed comprehensive systematic techno-economic analysis characteristics coaxial multi-external-chamber (MECC) GHEs compared to conventional double U-tube (2U) GHE. A three-dimensional numerical model was adopted...
