“…Sister holes is one of film cooling techniques that involves certain hole arrangements, and were introduced almost decade ago and has revealed a notable improvement in the thermal performance over a wide range of blowing ratios as well as a dramatic reduction on the strength of the counter-rotating vortices of the primary hole and maintained the coolant jet attached to the plate surface. The investigation reported in this chapter is different from all of the previous research available in open literature on sister holes film cooling, in such that a numerical prediction of the upstream sister holes thermal performance is carried out based on the only one experimental data avalibe on sister holes in the study of Wu et al [10]. The investigation is performed at low and high blowing ratios to examine the ability of several turbulence models and near-wall treatments to predict the upstream sister holes lateral performance.…”

“…The micro hole cooling performance will be investigated in terms of adiabatic film cooling effectiveness, including both centerlines and laterally averaged film cooling effectiveness, using equations (4.1) and (4.2), respectively. It has been found that the cylindrical cooling hole can be well captured using the realizable k-ε turbulence model as documented on the study of Zhang and Hassan [94], Balasubramaniyan and Jubran [23], Khajehhasani and Jubran [78], and Wu et al [10]. Therefore, the turbulent of the flow is presented thought the realizable k-ε (RKE) turbulence model, while the enhanced wall treatment (EWT) is selected for near-wall modeling.…”

“…Moreover, when two sister holes are placed slightly downstream of the primary hole ( Figure 2b), their jets generate an anti-CRVP, as illustrated in Figure 3b. Therefore, film-cooling effectiveness is increased by establishing vortex interactions between the jets and by reducing the intensity of the main CRVP [9][10][11][12]. The boundary conditions in each computational domain are specified in Table 1.…”

“…They found that the lateral distance and lateral ejection angles significantly influenced the film cooling performance while the effect of the streamwise distance on the film cooling effectiveness was considerably less. Wu et al [8] determined the cooling performance of three types of sister hole configurations by using experimental and numerical methods. They stated that the effectiveness of the film cooling was considerably higher for the triple-hole configurations compared with that for a single-hole configuration under steady flow conditions.…”
