| Abstract: | As the main accessory of the hydraulic system, the hydraulic tank has its structure and inflation parameters that have an significant effect on the separation and integration of bubbles and oil dissolved in the oil. Taking the special-shaped special fuel tank of the special vehicle as the research object, the Euler-Euler model in the multi-phase flow model in Fluent is used to perform a three-dimensional numerical simulation of the gas-liquid two-phase flow in the special-shaped oil tank internal flow field. Monitoring the change of the gas volume fraction at the outlet, studying the regular relationship between the air bubble and the oil integration under the effect of different inflation pressures, different speeds of the hydraulic pump in the hydraulic system tank, providing a reference for the design and selection of hydraulic oil tank and system. |
