Study of the Shape Optimization of the Connection Unit in a Modular Fuel Tank

Abstract

An important function of the modular fuel tank is rapid combination, as well as convenience of transport for both vehicle equipment and rescue personnel. This modular fuel tank has the function of transportation through the rope, which has certain advantages compared with the traditional 20 L oil barrel. In this paper, we designed a series parallel pump oil system that allowed for quick combination of the modular oil tank. With a DC electric pump, refueling gun, etc., it can form a temporary small oil depot. It can provide emergency fuel supply to disaster areas when energy transportation is blocked by natural disasters, such as earthquakes, floods, and debris flow. The first generation of the product met the basic requirements, but the efficiency of the system was relatively low, as the design and manufacturing cycle is too short. In this context, from the point of view of hydrodynamics, the components can be optimized through the analysis of the system. We used ANSYS Fluent to simulate the flow field, and compared the results with the experiment to determine the correctness of the relevant model. On this basis, the optimization design of the related components was carried out with topology, and flow field simulations were performed in order to get the optimized results. The simulation results showed that the flow rate of the improved system was 91.02 L/min, which is 3.13 L/min higher than the original 87.89 L/min, resulting in a 3.56% increase in efficiency.
