Effects of forward-flight speed on plume flow and infrared radiation of IRS-integrating helicopter

Zongyao Yang et al.

Summary: This study numerically investigated the effects of forward-flight speed on the exhaust plume flow and infrared radiation of an integrating infrared suppressor (IRS)-integrating helicopter. The results show that the interaction between forward-flight flow and downwash flow alters the exhaust plume development and the internal flow inside the IRS-integrating rear fuselage, and the influence of forward-flight speed on the overall infrared radiation intensity is complex due to the interaction between forward-flight flow and downwash flow.

Design of thermal cloaks with isotropic materials based on machine learning

Qingxiang Ji et al.

Summary: Thermal manipulation has been widely studied, and this research proposes a machine learning-based thermal cloak that uses isotropic materials in a finite number of layers. An artificial neural network is established to learn the relationship between the constitutive properties of each layer and the cloaking performances. The designed cloak demonstrates both ease of implementation and excellent thermal invisibility.

Temporally-adjustable radiative thermal diode based on metal-insulator phase change

Weixian Zhao et al.

Summary: Thermal diodes, which allow one-way heat transfer, have potential applications in thermal management, energy systems, and information processing. This study proposes a temporally-adjustable radiative thermal diode using vanadium dioxide and blackbody. The thermal rectification can be modulated with time based on the metal-insulator phase change. The shape factors influence the thermal rectification effect, with planar diodes showing stronger performance.

Robustly printable freeform thermal metamaterials

Wei Sha et al.

Summary: This study introduces printable freeform thermal metamaterials to address long-standing challenges in manipulating heat flow. Using topology optimization based on local thermal conductivity tensors, different functional cells are designed and 3D printed for concentrator, rotator, and cloak metadevices. The omnidirectional concentrating, rotating, and cloaking functionalities of these thermal metadevices are demonstrated numerically and experimentally, paving the way for advanced thermal metamaterials with complex shapes and fast-prototyping capability.

Inverse design of rotating metadevice for adaptive thermal cloaking

Zhan Zhu et al.

Summary: Thermal metamaterials with adaptive thermal cloaking effects have been studied, allowing for changes in thermal conductivity by adjusting the angular velocities of rotating layers rather than the configuration or constituent materials. This approach improves practicality and real-time application while providing insights for enhancing thermal cloaking effects in the future.
