This work covers three topics. Firstly, it summons a survey of available literature on simulation models of sensible and latent heat storages. Secondly, it describes a developed model for sensible or latent heat storage with Matlab simulation tool. Thirdly, it performs simulations for designing a pilot heat storage.
The development of simulation models in the field of energy technology surveys the simulation models of the sensible and latent heat storages. Thermal energy storage is a key technology in providing a balance between energy supply and demand for heating and cooling systems. Use of proper thermal energy storage systems presents a better solution for discrepancy between energy supply and demand. Heat transfer involving phase change is very important in latent heat storage applications. The numerical model and model based on number of transfer units method, proposed in this thesis, employ thermal distribution in phase change material and heat transfer fluid. The predication of temperature distribution and rate of melting or solidification is crucial in order to design latent heat storage devices. Phase change material melting time depends on not only thermal and geometric parameters, but also on the thermo-physical properties of the phase change materials.
