Abstract
Numerical study of heat transfer in a closed two-phase thermosyphon using the software package ANSYS FLUENT is carried out. Characteristic temperature distributions, current lines and velocity vectors are obtained at critical thermal loads. The temperature difference in the investigated region decreases with increasing heat load was obtained.
Highlights
Rechargeable batteries are one of the main parts of the emergency power supply system for aircraft [1, 2]
It should be noted that the system for removing heat from accumulator batteries based on two-phase closed thermosyphons has not been developed, since the theory of processes in the steam channel and the flowing fluid film has not been formulated
To verify the solution method used, the results of mathematical modeling were compared with experimental studies
Summary
Rechargeable batteries are one of the main parts of the emergency power supply system for aircraft [1, 2]. The use of these batteries in aviation technology is associated with the danger of an emergency This is confirmed by a number of firehazardous accidents on board the aircraft model Boeing 787 [4, 5]. It should be noted that the system for removing heat from accumulator batteries based on two-phase closed thermosyphons has not been developed, since the theory of processes in the steam channel and the flowing fluid film has not been formulated. Purpose of the work: mathematical modeling of the heat transfer process in two-phase closed thermosyphons at critical temperatures of rechargeable batteries of aircraft.
