Abstract:Based on the CFD theroy, the thermal insulation performance of the fuel tank under a certain generator train is simulated by STAR CCM+ in a given extremely cold working condition. Considering the effect of vehicle external flow field when the train is running, the coupling analysis is performed on the temperature distribution characteristics of the tank body, thermal insulation material, fuel oi, and so on, and the possible wax deposition regions of the fuel oil are found. The corresponding design conclusions and improvement suggestions are proposed, which provide reliable design reference for the stable working performance of the fuel tank.
Keywords:generator train  fuel tank  thermal insulation material  fuel oil wax deposition  CFD
