| dc.description.abstract | This study investigated the entropy production rate of turbulent distilled water flowing through three corrugated converging pipes of various corrugation amplitudes. The impact of the corrugation amplitude (0.02 โค ๐โ๐ท โค 0.03) and Reynolds number (0.5 ร 104 โค ๐ ๐ โค 4.0 ร 104) on entropy production rate (EPR) and Bejan number were examined. The finite volume method was utilised to solve the governing equations and the turbulent model (SST ๐ โ ๐ model), taking into account the boundary conditions stated in the ANSYS Fluent. The findings showed that increasing the corrugation amplitude and Reynolds number reduces the thermal entropy production rate, ๐๐กโ๐๐, compared to a straight pipe. On the contrary, as the aforementioned parameters increase the viscous entropy production, ๐๐ฃ๐๐ ๐, increases. Therefore, using corrugated converging pipe with enhance corrugation amplitude reduces the entropy production rate compared to a straight pipe. | |
