Résumé

Local heat transfer from single tubes in an industrial-sized, three-pass heat exchanger of the inclined tube bundle type was measured. The measurements were made using an electrically heated cylindrical probe of metallic film type. The probe was positioned at various tube locations and rotated to yield the circumferential variation of the local heat transfer. Depending on location, local mean heat transfer was less than half or more than twice the nominal mean value. These variations were related to the non-uniform flow distributions present inside the heat exchanger.
