EFFECT OF LATERAL FLOW EJECTION ON TURBULENT HEAT TRANSFER IN PIN FIN CHANNELS. Conference Paper uri icon

abstract

  • Experiments were conducted to study the effect of lateral flow ejection on the overall heat transfer for turbulent flow through pin fin channels. The two test sections of the investigation were rectangular channels with staggered arrays of six and eight streamwise rows of pins, respectively. The pin length-to-diameter ratio was one and both the streamwise and spanwise pin spacings were 2. 5 times the pin diameter. Heat transfer data were obtained for various ejection exit geometries, for ejection ratios between 0 and 1, and for Reynolds numbers between 6,000 and 60,000. The results of the study show that, for any given ejection ratio, the overall Nusselt number increases with increasing Reynolds number.
