The process of design of aviation heat exchangers occurs with an increase in the power stress and servicing energy systems that must be cooled. At moderate flight speeds, the systems of aviation engines, lubricants, and different equipment and optional energy systems can be cooled with heat exchangers using free air or other carriers.
25 Ιουν 2018 · This study compares the performance of conventionally-built plate-fin air–liquid crossflow heat exchangers (i.e., aircraft oil coolers) to additively manufactured heat exchangers of similar geometry.
1 Ιαν 2022 · In surface heat exchangers, the hot fluid (which could be, for example, oil, water, air, or some other cooling fluid) is directly in contact with the airframe skin, which, in turn, is directly in contact with the ambient air.
25 Νοε 2023 · The authors successfully replicated a conventional aircraft oil cooler HX design using AM techniques. The findings of this study revealed a high surface roughness in the additively manufactured component but demonstrated excellent accuracy in replicating the complex features of the original design.
26 Απρ 2017 · In this study, we focus on aerospace heat exchangers as a representative component and embark on the design and analysis of diverse fixture models that emulate their positioning within the...
heat exchanger concepts, namely, microchannel and phase change heat exchangers. Detailed conceptual design and performance models for these as well as for a conventional plate-fin compact heat exchanger are developed and their design and performance optimized relative to the criterion of minimum dry weight.
19 Σεπ 2024 · In order to enhance its heat transfer efficiency, a novel design featuring a shell-and-tube heat exchanger with disk-and-doughnut baffles and spiral dimple tubes (SDDD-STHX) is designed. Computational fluid dynamics is employed to compare this innovative design with the traditional smooth tube heat exchanger (STDD-STHX).
