... reduction. The purpose of this paper is to investigate the effects of transpiration on heat and drag reduction. Design/methodology/approach A chemical nonequilibrium flow model with the transpiration is established by using Navier–Stokes equations, the shear-stress transport turbulence model...

...Xiaolong Yang; Zhuangzhi Liu; Yu Hu Purpose The purpose of this paper is to investigate the mechanism and performance of a potential strategy, which is to enhance turbulence to carry out drag reduction for heavy trucks. Design/methodology/approach Enhancing turbulence deflector (ETD...

... can be reduced greatly by slip and the highest value of drag reduction (DR) (67.63%) can be obtained. The highest value of the increase in averaged Nu (11.78%) is obtained by slip at Re = 40 with volume fraction φ=0.01, which shows that super-hydrophobic surface can enhance heat transfer by slip...
