The computer simulation of a time-dependent process rests upon a discretized version of a mathematical model of the actual physical process. continu quantities, such as energy and temperature, are replaced by their values at discrete points. Time itself is discretized, and the marching process takes place through discrete time steps. The time steps for a computer simulation must be small enough for us not to lose the feeling of continuity [33]. The idea of the enthalpy approach is very simple, direct and physical. The volume occupied by the phase change material is divided into a finite number of control volumes and apply energy conservation to each control volume a discrete heat balance [33]. Equation 5-1 and 5-6 are solved a finite-difference solution method (FDM). The equation for the PCM is obtained upon integrating Equation 5-1 over the control volume in the (x, y) plane depicted in Figure 5-2 Figure 5-2 Grid point cluster (2D) The resulting scheme has the form (5-9) Where (5-10)
