dc.description.abstractIn this study, heat transfer and flow structures over protrusions in turbulent channel flow were systematically investigated by DES numerically. It is found that larger height ratio induces higher friction factor and heat transfer. However the performance factor, on the other hand, increases first then reaches its asymptotic limit and even decreases with an increase of height ratio. The highest local Nusselt number was found at the upstream portion of protrusion. Additionally, the local Nusselt number distribution is symmetric for low protrusion while asymmetric for high protrusion because of asymmetric flow structure. © 2012 American Institute of Physics.
