Mushatet Khudheyer 1 College of Engineering, Thiqar University, Nassiriya, IRAQ > Research Paper 2011 9 16 2012 -----Select---- 2 The heat transfer and fluid flow of multiple confined impinging jets impinge normally to the backward facing step cross flow hasbeen numerically investigated. Different sizes of impinging jets were tested while the channel contraction ratio(SR) was rangedfrom 0.25 to 0.5. The continuity, Navier-Stockes and energy equations were solved numerically. The discretized form of theseequations was obtained by using finite volume method with staggered grid technique. A Fortran built home computer codedepending on SIMPLE algorithm was developed to obtain the numerical results. The standard k-e model is used to treat theeffect of turbulence while the wall functions laws were used to treat the regions near the solid walls. The aim of this study is toshow how multiple confined impinging jets can be a controlling factor to enhance the rate of heat transfer form the hot surfaceof the channel backward facing step flow. The conducted results show that the heat transfer is enhanced significantly whenusing multiple impinging jets. The highest heat transfer was found closer to the region of the facing step. Also the results showthat the rate of heat transfer is increased as the jets sizes increase. Copyright@ International Science Community Association
