Modeling of heat transfer in inhomogeneous systems using the flow graph on the example of a lead-acid battery

Abstract

In this work, it is proposed to represent systems that are heterogeneous in terms of intensive parameters as a set of homogeneous subsystems between which extensive parameters are transferred. With this approach, it is possible to simplify the system by combining subsystems (or already the vertices of a graph) without losing its physical sense. This technique has been applied to simulate a lead acid battery.
