what is the fuel/oil heat exchanger and how does ice buildup affect things? The Fuel Cooled Oil Cooler (FCOC) / Fuel Oil Heat Exchanger (FOHE) exchanges heat between the engine oil and fuel streams. Heat is exchanged in such a manner that the engine oil is cooled whilst the fuel is heated up.
26 Απρ 2017 · The literature on aviation heat exchangers is voluminous and continues to be updated today. Two main aspects of this class of flow systems are widely investigated: fluid flow and heat transfer performances, and criteria for evaluating those performances.
The most common type employed is the indirect-contact heat exchanger. In direct-contact exchangers, heat transfer between fluids occurs through direct interaction, ideally without mixing or leakage. The fluids come into direct contact, exchange heat, and are then separated.
1 Σεπ 2018 · Thermal Science and Engineering Progress. Aircraft air conditioning heat exchangers and atmospheric fouling. Aircraft gas turbine start, lube oil is burnt, and oil vapour fouls other aircraft. Foulant debris is naturally occurring and from aircraft op’s (inc. vehicle op’s).
The Thermal Management Roadmap Report summarises the heat exchanger technologies considered essential for enabling zero-carbon liquid hydrogen fuelled aircraft. Competitive heat exchanger technologies are also outlined for later Entry Into Service (EIS) aircraft.
17 Ιαν 2008 · Fuel is then pumped through a Fuel/Oil Heat Exchanger (FOHE). The FOHE serves the dual purpose of cooling the engine oil, and raising the temperature of the fuel so that ice does not affect the downstream components, including the LP filter and the Fuel Metering Unit (FMU).
