“…Pechanek and Bouzek 13 applied CFD to study the cooling effect of the axial and circumferential water-cooling system. Saadi et al 14 studied the cooling performance of the fuel cooling system with a narrow flow channel. They found that the fuel cooling system increased turbulence and decreased the heat dissipation performance when increasing the velocity of fluid.…”

This paper designs an axial partition fuel cooling shell to solve the problem of temperature rise in the motor of the electric fuel pump (EFP). And describes a simplified method in conjunction with the computational fluid dynamics(CFD) to analyze heat generations and fuel cooling effects in integrated EFPs. Furthermore, CFD is used to numerically simulate the coupling effects among the fluid-solid-thermal based on multiple physical field. With varying different working conditions of the pump, cooling characteristics of the fuel cooling shell are obtained through CFD results. Finally, an experimental system for the EFP is established to verify reliability of the simplified method and the effectiveness of the fuel cooling scheme. Results show that fuel cooling shell plays an essential role in heat dissipating, with a maximum reduction of up to approximately 42 K in temperature. Temperature error between simulations and experiments is less than 4%, which indicates reliabilities of the simplified model and fuel cooling shell.

At present, vortex generators have been extensively used in radiators to improve the overall heat transfer performance. However, there is no research on the effect of vortex generators on the ends of motor coils. Meanwhile, the current research mainly concentrates on the attack angle, shape and size, and lacks a detailed study on the transverse and longitudinal distance and arrangement of vortex generators. In this paper, the improved dimensionless number is used as the key index to evaluate the overall performance of enhanced heat transfer. Firstly, the influence of the attack angle on heat transfer enhancement is discussed through a single pair of rectangular vortex generators, and the results demonstrate that the vortex generator with a 45° attack angle is superior. On this basis, we compare the effects of different longitudinal distances (2 h, 4 h, and 6 h, h meaning the height of vortex generator) on enhanced heat transfer under four distribution modes: Flow-Up (FU), Flow-Down (FU), Flow-Up-Down (FUD), Flow-Down-UP (FDU). Thereafter, the performances of different transverse distances (0.25 h, 0.5 h, and 0.75 h) of the vortex generators are numerically simulated. When comparing the longitudinal distances, FD with a longitudinal distance of 4 h (FD-4h) performs well when the Reynolds number is less than 4000, and FU with a longitudinal distance of 4 h (FU-4h) performs better when the Reynolds number is greater than 4000. Similarly, in the comparison of transverse distances, FD-4h still performs well when the Reynolds number is less than 4000, and FU with a longitudinal distance of 4 h and transverse distance of 0.5 h (FU-4h − 0.5h) is more prominent when the Reynolds number is greater than 4000.
