Abstract
Experimental and numerical study has been performed to study effect of swirl on heat transfer. A twisted swirl tape with twist ratio (T. R)=2 is used to generate swirl and effect of parameters like z/d=2 to 8 and Re varying between 3000 to 9000 are studied experimentally. Experiments show heat transfer dependency on Reynolds number. This study is further extended numerically using commercial CFD code ANSYS Fluent for much higher Reynolds number flow up to 20000. It is seen that CFD centerline peak Nu profile matches pretty well with experiments conducted. A relation between peak Nu and Re is established numerically for the conditions mentioned above. Further, effect of multiple swirl jet impingement (two jets separated by distance 1.5D, 2D and 3D) on Peak Nu is explained through CFD studies. CFD results show that jet distance of 1.5D is more effective in achieving higher heat transfer compared to 2D and 3D distances.
