An Analysis of Fuel Oil Sloshing in Partially Filled Cargo Tanker Trucks under Cornering Conditions Using Various Baffle Systems

Ethiopia imports all fuel and crude oils from abroad at high cost, transportation of these fluids has been carried out by using various capacity road heavy-duty truck vehicle. Most tanker accidents happen during turning because the fluid splashing in partially loaded tanks uniqueness carrying liquids. This is a result fact that current baffle configurations are effective reducing sloshing when braking or accelerating but ineffective doing so turning. Consequently, primary goal this thesis work to investigate how different systems affect lateral reduction. In work, optimal configuration its arrangements for modified oval 50% 80% fill levels were tried, dynamic analysis trucks was researched. The system designed CATIA V5 numerical analysis, CFD study completed ANSYS Fluent 2021. R2 LS-DYNA stability truck. computational simulation as tank with eight types such existing baffles (TB), TB BMLB, UMLB, CLB, 2HLB, 2VHLB, 4HLB, 4VHLB similar meshing resolution, turbulence modeling, boundary conditions, also solution strategies. Transverse bottom-mounted four holes longitudinal hole-varying position (4VHLB) discovered be best type after evaluating designs. suggests quantity reduced number small diameters increases. Maximum force roll moment most, 47.76% 58.66%, respectively, level 58.08% 22.52%, level. case truck’s use revised design will crucial enhancing rollover while cornering.
