However, traditional heat transfer design for specific operating conditions can only meet thermal demands by adjusting external pipes and window openings, which is often insufficient. To address this issue, we propose an adaptive heat exchanger with shape memory alloy (SMA) as the thermal source generating structure. This study combines numerical simulations and flow heat transfer experiments to investigate the optimization of the adaptive heat exchanger by adjusting the SMA arrangement spacing and perforation design. The results show that reducing the SMA spacing Δ<em>X</em> (from 11 mm to 7 mm), the heat exchanger can significantly reduce the internal fluid dimensions and increase the secondary flow velocity. This not only enhances the heat transfer capability but also increases flow resistance. The maximum <em>PEC</em> value increased from 1.369 (<em>Re</em> = 2000) to 1.474, with a 7.7 % improvement in overall performance. Additionally, the heat transfer adjustment capability <em>K</em><sub><em>Nu</em></sub> and flow resistance adjustment capability <em>K</em><sub><em>f</em></sub> increased by 12.1 % and 38.0 % respectively (<em>Re</em> = 3000). Additionally, perforating the SMA strips improves the flow conditions between the SMA and the heat exchanger wall, significantly reducing the flow dead zone. Among the five perforation designs studied, elliptical perforation structures performed the best. When the SMA strips are fully deflected (Δ<em>Z</em> = 5 mm), the heat transfer adjustment capability of the elliptical perforation structure Δ<em>X</em> = 11 mm increased by 9.25 %, and the flow resistance decreased by 29.8 %.

The PCM within the cavity was initially superheated. A constant temperature condition lower than the melting temperature was applied uniformly to the circumferential wall of the cavity via a water jacket. Three experimental measurement techniques were implemented. The first two techniques were used in conjunction to estimate the internal temperature of the PCM and, by extension, the transient temperature fields within the solidifying PCM. These temperature-measuring techniques provided data from a high-resolution grid of thermocouples and a novel technique using an infrared camera.

Recent studies highlight the significant impact of internal supply configurations on the aerodynamic and thermal characteristics of external film cooling. Therefore, this study investigates the aerodynamic and heat transfer performance of double-jet film-cooling holes under crossflow conditions, both with and without ribs, through numerical simulation. The study examines both positive and negative crossflow supply directions across four blowing ratios (ranging from M = 0.5 to 2.0), using a cavity supply case as the baseline for comparison. By modifying the geometric and aerodynamic boundary conditions, the focus is on analyzing the changes in the flow field structure, aerodynamic losses, and cooling performance across various supply configurations. The results reveal that at low blowing ratios, double-jet film-cooling holes are significantly affected by crossflow. Compared to the cavity supply case, the discharge coefficient in the crossflow cases decreases by up to 45.1 %. Different internal crossflow supply configurations exhibit distinct optimal blowing ratios, with the smooth crossflow supply configurations beginning to demonstrate advantages in cooling performance when M ≥ 2.0. This research emphasizes the importance of a rational configuration of the cooling structure—including the internal structure, supply direction, and hole parameters—for substantially enhancing film cooling performance under high blowing ratios (M ≥ 1.5).
