Simulation of Liquid Fuel Spills Combustion Dynamics Based on Computational Fluid Dynamics Using Modern Application Programs

Abstract

The article presents the results of calculations using modern application programs, using the CFD FDS 6.3 model, self-sustaining burning of liquid hydrocarbon fuel spills with a sufficiently high accuracy for spills less than 0.5m in diameter. The study shows that the use of modern software systems for CFD modeling, taking into account wind direction, humidity and other environmental parameters, significantly reduces the costs of risk assessment in emergency situations associated with the use of LNG in transport. Conducted research allows to increase reliability and reduce risks of liquefied natural gas usage in transport

Systematic study of structural divisions of industrial enterprise using queuing systems

“…To determine the nominal mode of operation of the model, it is necessary to select several informative performance indicators by which it will be possible to evaluate efficiency of the model (Afanasev, P.M., 2020). Let us choose the following indicators: utilization rate, average number of applications in the queue, average waiting time for applications in the queue, average number of busy channels.…”
