Investigation of the pipe diameter modulation effect and pressure drop prediction for R245fa gas-phase flow based on the Kriging surrogate mode
In Organic Rankine Cycle (ORC) systems, the frictional pressure drop along transportation pipelines serves as a critical factor contributing to systemic irreversibility (exergy loss). This study focuses on R245fa as the working fluid and conducts a parametric investigation into its low-pressure gas-phase flow character...
