... equation given by Eq. (3) [ 27 ] (3) q C O N V = h c A ( T H − T C ) For the 3D model heat transfer governing equations, the basic convection, conduction, and radiation equations are considered. The basic 3D steady-state heat conduction equation in the cartesian...

... of these variables and the S parameter of the abovementioned logistic function. The amplification parameter S , recognized as the most interesting to evaluate the TES effectiveness in storing thermal energy, is now related to the radius, thanks to our 3D model. On the other hand, since we investigated...
