Special Issue Information

Dear Colleagues,

Thermal management and heat transfer play a critical role in ensuring the efficient and reliable operation of aero-devices. With advancements in technology and increasing demands for high-performance aerospace systems, the study of thermal management has become a vital area of research. This field focuses on understanding and optimizing the heat dissipation, thermal insulation, and temperature control mechanisms within aero-devices, such as aircraft engines, gas turbines, and spacecraft components.

Efficient thermal management is crucial for enhancing the overall performance, extending the lifespan, and ensuring the safety of aero-devices. It involves the utilization of advanced materials, innovative cooling techniques, and sophisticated heat transfer analysis. Researchers and engineers strive to develop effective thermal management solutions that can handle the extreme operating conditions experienced by aero-devices, including high temperatures, high pressures, and rapid thermal fluctuations.

Cutting-edge topics in thermal management and heat transfer research include:

Active cooling techniques using microchannels, heat pipes and spray cooling.

Thermoelectric materials for waste heat recovery in aero-devices.

Computational fluid dynamics (CFD) simulations for optimizing heat transfer in aerospace systems.

Additive manufacturing of heat transfer components with complex geometries.

Thermal management of electric propulsion systems in aircraft.

Thermal interface materials for improved heat dissipation in aero-devices.

Thermal analysis and design of hypersonic vehicles.

Thermal management strategies for unmanned aerial vehicles (UAVs) and drones.

These topics represent the forefront of research in thermal management and heat transfer in aero-devices, addressing the challenges posed by evolving aerospace technologies.

To enhance the heat-transfer performance of scramjet engines, a numerical simulation was conducted on the heat-transfer process of RP-3 aviation kerosene under supercritical pressure within a horizontal micro-fine circular tube. The intrinsic mechanism of the heat-transfer process was analyzed, summarizing the impacts of mass flux, inlet temperature, and gravitational acceleration. Furthermore, four commonly used buoyancy criterion numbers were compared and evaluated. The results indicate that the heat-transfer process can be divided into five phases: heating inlet phase, normal heat-transfer phase, heat-transfer deterioration phase, heat-transfer enhancement phase, and high-temperature normal heat-transfer phase. The heating inlet phase is significantly influenced by the inlet temperature, while the heat-transfer deterioration is affected both by the thermal property variations of the aviation kerosene and the buoyancy effects. Lower mass flux and hypergravity conditions all exacerbate heat-transfer deterioration. Inlet temperature, however, does not affect the heat-transfer pattern. Among the criteria, Grq/Grth provides the best prediction of buoyancy effects in horizontal circular tubes. Full article
