RESUMO

This work presents an analytical model to describe the dynamic behaviour of a sensible heat storage of parallel plate type. The physical mode! is composed of parallel of a set of thick parallel sheets arranged such that the transport fluid flows in between. The analytical model is based upon the equation of energy for the transport fluid and the two dimensional heat conduction equation for the solid plates together with the adequate boundary and initial conditions. The set of equations were solved numerically for different operational and geometrical parameters by using a finite difference scheme. In order to confirm the numerical results an experimental rig was designed, constructed and instrumented to test modular storage units under various operational conditions. Numerical results were compared with experiments and good agreement was found. It is included in this work a technical and economic analysis of a heat storage in real work s conditions to implant imediatelly in steel industry
