“…The flow field simulation analysis is carried out through the establishment of different inlet grille opening and closing angle models, and the influence law of grille opening on vehicle C D value is studied, so as to optimize the wind resistance of vehicle and the heat dissipation performance of engine compartment. In the study of the fluid mechanics performance characteristics of small mobile vehicles, Sun et al [21] also used CFD technology to simulate the fluid mechanics and performance characteristics of the new elastic blade/wave energy converter, which is similar to the method of this exploration and provides support for this exploration.…”

Computational Fluid Dynamics is used to assess the thermal (heat transfer) performances of an automobile engine considering different grille opening and closing degrees. For this purpose the entire vehicle is modelled and three fundamental aspects are examined, namely, the open area of the air intake grille, the position of the upper and lower grilles and their shape. The results show that the opening area and position of the grille have some influence also on the aerodynamic characteristics of the automobile. With an increase in the opening angle of the grille, the C D (Drag Coefficient) value of the whole vehicle becomes higher. When the air intake grille of the car is fully open or closed, the C D value is 0.35434 or 0.31777, respectively, that is, the flow resistance in the engine compartment accounts for 10.32% of the C D value for the whole automobile.

“…A Li-ion Battery is a kind of high-efficiency recyclable battery, which mainly depends on the insertion and removal of lithium ions between the positive and negative electrodes in the battery to complete the charge and discharge (that is, the storage and release of electric energy) [5]. The packaging methods of the commercial power of Li-ion batteries are generally divided into winding packaging or stacking packaging.…”

“…The fixed support is used to apply a centrifugal load to the blade. Meanwhile, the blade pressure data obtained by the fluid simulation are imported, and the aerodynamic loads in various directions are simultaneously applied to the surface of the blade to perform fluid-solid coupling static force [28,29]. The specific loading process is shown in Fig.…”

Taking a two-stage variable-pitch axial fan as the research object, five schemes, including a single counter-flow rib layout grooved tip, are numerically simulated using the fluent software. The results indicate that, compared with the original blade tip, the total pressure rise and efficiency of the four proposed schemes have been improved to various degrees, with Scheme 4 (groove tip with double counterflow ribs) displaying the best performances. The total pressure and efficiency are increased by 113.44 Pa and 0.955%, respectively. The blade tip leakage flow is reduced to varying degrees under different schemes, according to the following order: Scheme 1, Scheme 2, Scheme 4, and Scheme 3 leading to a reduction of 7.44%, 6.46%, 5.36%, and 4.35%, respectively. Steady results are used as the initial condition for the ensuing strength check and modal analysis.
