DEVELOPMENT OF A DISCRETE MATHEMATICAL MODEL OF THE HYDROTREATING DIESEL FUEL REACTOR by Ksenia Igorevna Netsvetaeva

“…The article gives an example of the transformation of the initial mathematical model of the hydrotreating diesel fuel reactor which is a system of algebraic equations into its discrete analogue, using the method of "nets" (finite difference method). The transformation of the original system was made because of the complexity of solving it explicitly and the need to obtain the most accurate values of the variables.…”
