“…The purpose of the investigation is to analyze the influence of the configuration of lateral baffle installed in the road tank on the characteristics of liquid cargo sloshing in the reservoir at its emergency braking. This work is a continuation of the research published in [18][19][20]. In these papers it was demonstrated that total liquid energy dissipation can be used as the criterion of the damping efficiency of liquid cargo oscillations in the reservoir and there was performed the analysis of finite element sizes' influence on the accuracy of computational results.…”

The purpose of the investigation is to analyze the influence of the configuration of lateral baffle installed in the reservoir of road tank on the characteristics of liquid cargo sloshing in the tank at its emergency braking. There were performed computations for the analysis of the hydrodynamic pressures and liquid energy dissipation for different kinds of liquid cargo transported in the road tanks with perforated and solid baffles. Also different filling levels of the reservoir were considered. The configuration of the internal lateral baffle providing maximal efficiency of liquid oscillations damping and minimal loading of the road tank shell was suggested.

The article presents the analysis of the 1D flow of compressible fluid by means of analytical and numerical methods. The results from the solution showed that the calculation of dimensionless velocity for particular flow conditions varies in the area of subsonic flow only a very little, when using both methods. It was found that the dependence of dimensionless velocity on the relative duration of the investigated tunnel applies universally. For any proportional value of the tunnel length x/L and the constant ratio of outlet and inlet cross section of the tunnel level equal to 0.6474, the course of the dimensionless velocity for each tunnel, which satisfies the above condition, will always be the same. This means that also the nature of flow in any such tunnel will exhibit the same properties. This finding provides new knowledge from the analysis of air flow through a channel with a variable flow cross section.

“…The results showed that the use of bulkheads reduced the maximum coupler force by 70%, decreased the amplitude of the sloshing oscillation, and led to an even distribution of the normal contact force on the wheels. Shimanovsky et al (2014) performed finite element analysis and studied the oscillations of Newtonian and non-Newtonian liquids in a cylindrical transport reservoir during braking. In this regard, the characteristics of Newtonian, Ostwald de Waele, and Bingham models of sloshing liquid in the tank with/without internal perforated baffles were analyzed and the relationship between the hydrodynamic pressure and the energy dissipation rate of studied fluids with different filling levels was extracted.…”

Tuned liquid dampers (TLDs) have been broadly applied to suppress structural vibrations. In the present study, a novel vibration mitigation device consisting of non-Newtonian fluids coupled with an elastic baffle is proposed. The fluid-structure interaction is studied numerically. To optimize the system, different fluids, including the Bingham fluid, the Pseudoplastic fluid, and the Dilatant fluid are used as the damping fluids and the vibration suppression ability of each fluid is studied. Moreover, the energy dissipation mechanisms of different liquids are obtained. The results show that the optimal vibration suppression in the container without a baffle can be achieved by using the Bingham fluid. In this case, the average amplitude decay rate of the container is 12.662% with about 0.199% improvement in the damping ratio when compared to water. In the container with an elastic baffle, however, both the Pseudoplastic fluid and the Dilatant fluid outperform water in the damping capacity. The average amplitude decay rates of these fluids are 50.960% and 43.794%, respectively. Moreover, their damping ratios are 0.035% and 0.019% higher than that of water, respectively.
