| Abstract | ||||
| This paper presents an experimental investigation of heat transfer and hydrodynamic resistance of gasecris plate heat exchangers type diffuser-confuser . The test section was a slotted channel and consisted of two horizontally located heated copper plates with dimensions 1000 x 200 x 15mm. The diffusers flare angle was 12o and lengths of diffusers and confusers were 8 and 4 mm respectively, Symmetric and asymmetric channels were studied with different heights during turbulent motion of air. The heat transfer data for these channels shows that intensification of heat transfer is gained with moderate growth of resistance. Some correlations are obtained for calculating the nest transfer coefficient and the hydrodynamic resistan | ||||
