With higher transfer rate required, many researchers have shifted their attention towards boiling heat transfer that offer superior transfer rate. Despite its potential, study on this heat transfer process have not been as extensive as its single-phase counterpart. Particularly, to the best of our knowledge, no study on the boiling heat transfer in oval tube with different ellipticity. Thus, Numerical investigation using RPI wall boiling model and RNG k-ε turbulence model is conducted for different ellipticity of the oval tube. It is found that the heat transfer performance drop as the ellipticity increases with constant perimeter. Decrease of heat flux and increase of mass flow rate have positive impacts toward the heat transfer performance. The vapour generation resulting by the heat flux and mass flow rate is having high influence in the heat transfer coefficient and pressure drop. © The Electrochemical Society date: 2022 publisher: Institute of Physics official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85130541011&doi=10.1149%2f10701.1919ecst&partnerID=40&md5=705b9f3689e18cf8b68cd15af07b5cbd id_number: 10.1149/10701.1919ecst full_text_status: none publication: ECS Transactions volume: 107 number: 1 pagerange: 1919-1931 refereed: TRUE isbn: 9781607685395 issn: 19386737 citation: Liaw, K.L. and Kurnia, J.C.
