“…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.

“…They demonstrated that porosity, submergence depth and baﬄe location are important design parameters. Kuzniatsova and Shimanovsky 28 investigated the performance of perforated baffles in reducing the liquid oscillation and fluid impact in liquid containment systems used by road vehicles and proposed an optimal size of the porous hole size and area. Cho et al 29 showed that horizontal porous baﬄes installed at the side walls are more effective in terms of suppressing sloshing.…”

This paper examines the influence of oblique perforated baffles on the sloshing dynamics of rectangular liquid storage tanks. The analysis presented accounts for sway induced hydrodynamic forces and entropy generation. Internal liquid free surface oscillation is modelled by the volume of fluid method. The effect of baffle geometric parameters, orientation and porosity on loads is examined and numerical results are compared against a set of experiments. Consequently, an engineering method suggesting the optimum size, angle of inclination and topology of baffles for the case of a rectangular tank is presented. It is shown that implementation of optimized oblique porous dual baffles may reduce sloshing loads by up to 15%.

“…Kumar and Sinhamahapatra [19] analyzed the dynamic effects of single-opening slotted type baffles. Kuzniatsova and Shimanovsky [20] illustrated the geometry of perforated-type baffles to provide minimal equivalent stresses and maximal liquid oscillations damping in a tank reservoir. Zhang et al [21] reported a heat and fluid characteristic comparison between heat exchangers with various deflectors, i.e.…”

In the present analysis, a new geometry of obstacles is considered in order to demonstrate its importance in improving the thermal-hydrodynamic performance of hydrogen fluid within a 2D, rectangular section channel subject to a constant surface temperature condition along its hot top wall. The new obstacle has a variable-position square-shaped gap (called: perforated obstacle), to reduce its resistance to the fluid flow, to decrease the skin friction, in order to determine the optimum configuration for a high heat transfer. This gap has three different positions (dg) in the (h) height baffle section, i.e., dg = 0.25h, 0.5h and 0.75h reported, respectively, as A, B and C types. The governing equations among the fluid and solid sections are determined and solved via the finite volume method (FVM). The obtained results are presented for Re = 5 × 103-2 × 104. The thermal improvement factors of the channel containing the perforated baffle appear to be greater than unity for all dg gap positions situated between 1.143 and 4.236, and dependent on the values of dg and Re, which suggest a better thermo-hydrodynamic performance compared to that obtained with a smooth channel. It is found that the thermo-hydrodynamic improvement value in case C of a 0.75h perforated baffle decreases by 2.747% compared to the case of a simple obstacle with no gap, at Re = 2 × 104. However, the value of this same factor increases by 5.901% and 2.794% when the value of dg is equal to 0.25h and 0.5h, respectively, for this same great value of the Reynolds number. Therefore, the perforated baffle model with a small gap position distance (dg = 0.25h) can be selected as the best geometric model for a good thermal improvement with minimal frictions inside the channel. The subject is relevant and important for industrial applications.
