“…The main problem issue in the operation of equipment for storage and transportation cryofuel is the study of thermodynamic processes inside a cryogenic tank, for which computer modeling systems are currently used [13][14][15]. The process of solving the system of equations of hydrodynamic processes and heat and mass transfer processes during storage of cryofuel in a container requires serious computational resources, and the duration of a numerical solution can reach several days or weeks even for simplified models [2,[16][17][18]. Because of this, it was proposed a separate tasks of determining the main thermophysical parameters of a cryofuel in the vapor space of a tank or container and calculating the holding time of cryofuel [2,19,20].…”

“…Instead, the interaction of the computational module with the main database of calculated values of pressure and temperature was established. The accumulation of this database was carried out beforehand according to the CFD results of modeling in the form of unsteady temperature fields and pressures in the vapor space of the inner tank [6,15,18,22]. The modeling results can be obtained in both commercial software (ANSYS Fluent, STAR CCM+, COMSOL Multiphysics) and open-source systems (OpenFOAM).…”

The problem issues of non-drainage storage of cryogenic fuels in modern modular long-term storage systems are considered. The structure of software for remote monitoring the container and small-scale reservoir equipment for storage and transportation of cryogenic fuel is presented. The relationship of software modules for computational modeling of hydrodynamic and thermodynamic processes during storage of cryogenic fuel in stationary and transport conditions, a module for calculating the holding time of non-drainage storage, and individual data transmission modules installed on cryogenic tanks are disclosed. The composition of the software of operators responsible for remote monitoring of the state of multimodal transport units during transportation and long-term storage at the point of consumption is described. An example of energy-efficient technical solution for increasing the holding time of non-drainage storage of liquefied natural gas during storage and transportation in multimodal transport units are considered. In the autonomous power supply system of the multimodal transport unit under consideration, the conversion of solar energy is used to charge accumulator batteries. The results of calculations of electricity consumption for increasing the holding time up to values of 150-200 days, demanded by consumers of cryogenic fuel, are presented.
