Simulation of the heat accumulator operation of the internal combustion engine preheating system

We considered the heat accumulator with a phase-transfer heat-accumulating material, which serves for pre-heating of the car’s internal combustion engine. Simulation of the heat accumulator operation allows to build calculated graphs of temperature change of the heat-accumulating material in time, a...
