The world energy consumption is greatly influenced by the aviation industry with a total energy consumption ranging between 2.5% and 5%. Currently, liquid fossil fuel, which releases various types of Greenhouse Gas (GHG) emissions, is the main fuel in the aviation industry. As the aviation industry grows rapidly to meet the requirements of the increased world population, the demand for environmentally friendly power technology for various applications in the aviation sector has been increased sharply in recent years. Among the various clean power sources, energy obtained from hydrogen is considered the future for energy generation in the aviation industry due to its cleanness and abundance. This paper aims to give an overview of the potential aviation applications where hydrogen and fuel cell technology can be used. Also, the major challenges that limit the wide adoption of hydrogen technology in aviation are highlighted and future research prospects are identified.

“…The PDWICs were adjusted from 51.90 kPa to 235. 35 , and the test data was attained under the steady-state condition. Characteristic curves of the heat transfer coefficient as a function of PDWIC and surface temperature as a function of PDWIC are shown in Figure 7a As shown in Figure 7, it can be obviously observed from the pattern (a) that the heat transfer coefficient displays an upward tendency with different slopes as the PDWIC increases because of the droplet-enlarging dissipate more waste heat [20].…”

“…As is known to all, the aircraft auxiliary power unit (APU), which consists of a small gas-turbine, is a system designed to supply part of electrical and pneumatic of aircraft. The unit is not limited to start the airplane's main aeroengines, but also provides pneumatic such as aircraft pressurizing [35]. Therefore, the high-pressure air is so available [7] that could provide the primary gas-flow for SCS.…”

This paper presents an air-oriented spray cooling system (SCS) integrated with a two-phase ejector for the thermal management system. Considering its aeronautical application, the spray nozzle in the SCS is an air-blast one. Heat transfer performance (HTP) of air-water spray cooling was studied experimentally on the basis of the ground-based test. Factors including pressure difference between water-inlet-pressure (WIP) and spray cavity one (PDWIC) and the spray volumetric flow rate (SVFR) were investigated and discussed. Under a constant operating condition, the cooling capacity can be promoted by the growth factors of the PDWIC and SVFR with the values from 51.90 kPa to 235.35 kPa and 3.91 L ⋅ h − 1 to 14.53 L ⋅ h − 1 , respectively. Under the same heating power, HTP is proportional to the two dimensionless parameters Reynolds number and Weber number due to the growth of droplet-impacting velocity and droplet size as the increasing of PDWIC or SVFR. Additionally, compared with the factor of the droplet size, the HTP is more sensitive to the variation in the droplet-impacting velocity. Based on the experimental data, an empirical experimental correlation for the prediction of the dimensionless parameter Nusselt number in the non-boiling region with the relative error of only ± 10 % was obtained based on the least square method.
