...Guoqing Li; Ang Li; Shen Zhang; Chenfeng Wang; Xingen Lu Under the influence of secondary flow, the film cooling deviates from the flow direction on the turbine blade, which directly results in undesirable uneven film coverage. On the pressure side, the film appears divergent, while on the suction...

... value, which is called the “crest value” for the axial velocity. The crest value is the result of the boundary layer, secondary flow, and stochastic motion caused by the turbulence. Second, in the heated zone, the axial velocity is constant for the constant properties fluid, but increases gradually...

...—termed as the short channel. Multiple secondary flow patterns develop in the curved section of the channel, which in conjunction with the bulk axial flow, lead to the formation of multiple vortices and separation bubbles. The complex 3-D flow structures, as well as the variable c/s area of the curved...

... are systematically evaluated, and the heat transfer and pressure loss characteristics are investigated. It is found that counter-rotating streamwise vortices are induced by the wavy walls, and the flow field has been drastically modified due to the intense secondary flow. By using the optimum set of oblique angle...
