Summary: Based on a combined-hole design, a new hole arrangement was proposed and tested on a flat plate model by numerical simulation. The new hole arrangement, which replaces one row of staggered holes with a row of smaller holes, enhances the film cooling performance by weakening the interaction between vortex pairs. Compared to the original hole arrangement, the new arrangement reduces the coolant mass flowrate by 25% and maintains similar or even higher film cooling effectiveness at different blowing ratios. However, at a blowing ratio of 1.5, the film cooling performance of the new arrangement is not as good as the original one due to weakened coolant accumulation and reattachment phenomenon.

Summary: Numerical simulations were conducted to investigate the effects of plasma actuators on film cooling enhancement and flow characteristics around film holes. The results showed that opening the plasma actuators reduced the backflow region and the intensity and scale of vortices. The applied voltage affected the flow attachment location and the height of the coolant air, and the plasma injection increased the turbulent kinetic energy near the wall. The film cooling effectiveness increased significantly on the pressure side and had minimal effect on the suction side. The sensitivity of the applied voltage decreased with increasing blowing ratio.

Summary: This study experimentally and numerically evaluates the overall film cooling performances of double-jet film cooling (DJFC) holes on a flat plate, including the film cooling effectiveness (eta), heat transfer coefficient (HTC) ratio, and the net heat flux reduction (NHFR) parameter. The spanwise distance (p/d) varied as 0.5, 1.0, 1.5, while the streamwise distance (s/d) remained at 3.0. The results show that p/d = 0.5 has the highest cooling effectiveness and net heat flux reduction parameter among all configurations. At low blowing ratios, all DJFC configurations exhibit high film cooling effectiveness and positive NHFR values. However, the NHFR becomes negative for p/d = 1.0, 1.5 at high blowing ratios, indicating that the increased heat flux is larger than without film cooling. The film effectiveness distribution is significantly influenced by the anti-kidney vortex, which is related to p/d and blowing ratios (M). The heat transfer coefficient ratio profile is mainly affected by the turbulent kinetic energy (TKE) enhanced by the jet interaction.

Summary: Due to advancements in micro manufacturing and 3D printing, the complex shape of microchannel heat sinks (MCHS) can now be achieved, allowing for improved heat transfer characteristics. In this study, a twisted tube geometry was applied to microchannels and the thermal and hydrodynamic performance of twisted square microchannels with jet impingement was investigated. The arrangement of the jet channels was studied, comparing one-jet and multi-jet microchannel heat sinks in terms of temperature profile, pressure drop, and heat transfer characteristics. The results showed that applying the twisted geometry increased the Nusselt number by 16.48% with minimal pressure drop increase. Furthermore, integrating jet impingement improved the thermal-hydrodynamic performance of MCHS, reducing thermal resistance by up to 41%. Finally, it was concluded that jet arrangement at torsion angles of 45 degrees, 135 degrees, and 225 degrees provided better performance. This study provides quantitative characterization of MCHS performance and guidance for jet arrangement design.

Summary: In this paper, an improved periodic cellular material (XCCH) that combines X-lattice with corrugated honeycomb is proposed. Comparisons with the X-lattice cored plate honeycomb (XCPH) show that the XCCH has higher compressive strength and convective heat transfer characteristics.

The introduction of corrugated fins improves turbulent kinetic energy and enhances heat transfer. Additionally, the XCCH has 20% higher compressive strength due to increased moment of inertia and improved energy absorption ability.
