Abstract: Many scientific researchers are studying the physical properties of concrete with the aim of proposing a type that provides better thermal insulation for the construction of high-temperature storage reservoirs. In the literature, there are several types of concrete, each depending on the percentages and constituent components.
In this work, the objective is to assess the thermal properties of concrete formed from different types of aggregates for cylindrical-shaped storage reservoirs. We aim to understand the influence of temperature variation (at high temperatures) and the thermal behaviors of storage reservoirs constructed with different thicknesses. To achieve this, we employed finite difference modeling to derive results regarding temperature variation in the reservoirs for different thicknesses.
We compared three reservoirs with the same radius but different thickness values: 15cm, 20cm, and 25cm. It was observed that, from the center of the reservoir outwards, the temperature consistently decreased over time. Subsequently, we conducted simulations using the COMSOL Multiphysics software to illustrate temperature changes over time at each point within the studied reservoir and to compare our analytical results with our numerical findings.
