This complex zone, which is composed of two regions of elevated Nusselt number that surround a region of lower Nusselt number, is caused by the tip leakage vortex. A final feature of interest runs along the suction side immediately downstream of the rim.However, it is clearly visible in the results of Kwak and Han, which also featured double squealer rims. This phenomenon was not seen by Rhee et al. This effect was observed by both the experiments and the CFD. Another zone of elevated Nusselt number occurs along the SS squealer and can be easily explained by the acceleration effect induced by the rim.These features were not well-captured by the CFD, which only shows a wider high- Nusselt zone with increasing gap height. These features can also be seen in the results of Rhee et al. When the tip gap clearance was increased, the zone with lower Nusselt number grew in size while the zone with higher Nusselt was shifted towards the SS squealer rim. Immediately downstream of the PS rim and parallel to it, a pair of features can be recognized as two consecutives zones, the first showing decreased Nusselt number, and the next showing increased Nusselt number.The CFD tends to overestimate this increase in Nusselt on the squealer rim. This feature can also be seen in the results of Rhee et al.

There is a rise in Nusselt number right above the PS squealer rim, which corresponds well to flow entrance effects and to the acceleration of the flow.

This is most likely due to stagnation at the leading edge coupled with the flow contraction within the tip gap. For the smaller tip clearance, much higher values of Nusselt number can be seen. This region is shown by the simulations and the experimental results for all clearance heights. At the blade LE, a small region of enhanced Nusselt number can be seen.Figure 11 shows a better representation of the passage distribution. The CFD simulations seem to slightly overestimate the heat transfer coefficients in this region compared to the experimental results. In the passages between the blades, lower Nusselt numbers can be observed for both the computations and the experiments.The Nusselt number is defined using the following equation: 2D distributions of the Nusselt number on the heat shield surface are shown in Figure 7, Figure 8 and Figure 9, for both the numerical and experimental results. from both the numerical and the experimental study are compared. These results reveal considerable potential for error in assuming that smooth films are necessarily structurally uniform material structure may spatially vary for some coating methods, leading to a correlated, spatially varying device performance. The potential for long-wavelength instabilities to create device-relevant morphology variations should be considered when optimizing coating conditions. Hole mobility is directly correlated to the local alignment and shows an ≈2 × variation across the instability for devices aligned with the coating direction. By correlating measurements over diverse (nm to mm) length scales, we can directly relate the charge transport in top-gate transistors to the local polymer nanofibril alignment. We report on a long-wavelength instability during blade coating of a semiconducting polymer/elastomer blend for organic transistor applications that results in significant variation of the semiconducting polymer nanofibril alignment across the instability period. Similarly, meniscus-guided coating can be used to tailor electrical properties through alignment of the semiconducting material.

The use of polymer–polymer blends to tailor mechanical properties and improve electrical performance is becoming widespread in the field of printed electronics.
