Abstract

The material presents the results of numerical modeling of internal fluid flows geometry in tanks that are subject to fluctuations due to external force influences. Similar applied problems occur when transporting large volumes of liquid, for example, in tanker ships. Given the rather significant moving masses within the reservoirs (tanks), as a rule, there are shock pressures on the walls and internal structures of the guiding devices, which can cause their deformation and even destruction, which leads to serious emergency situations.
Numerous studies devoted to the determination of the force effects of liquid flows on the walls of tanks came to the conclusion that the presented phenomena are of a strongly nonlinear nature, depend not only on the amount of liquid and the directions of its movement within the tank, but also on the formation of velocity and pressure fields over time. The specified parameters are decisive in predicting possible resonance phenomena in tanks, which in turn can become the main factor in the design of means of damping or control of inertial fluid flows.
The proposed work is devoted to the mathematical modeling of the mentioned phenomena in tanks, as well as the analysis of the force effect of internal inertial flows, which cause the occurrence of shock pressures on internal structures. On the basis of the indicated research results, it is possible to propose rational from the point of view of damping the design of guide devices in the form of flat rigid baffles.
