TEMPERATURE DISTRIBUTION OR HEAT DISTRIBUTION IN A CYLINDRICAL ENERGY STORE

A temperature or heat distribution is to be determined in a cylindrical energy store (1) in a simple way. To this end, the structure of the energy store (1) is described by way of an arrangement of a plurality of hollow cylinders (2) which lie coaxially in one another and/or on one another or of a plurality of part cylinders which lie one another coaxially and/or in parallel with regard to the axes thereof. A respective temperature or heat quantity of each hollow cylinder (2) or part cylinder is determined, wherein a quasi-static state is assumed in each hollow cylinder or part cylinder along a time series at each individual observation time.
