Abstract: To develop a precise and efficient computer model for predicting the heating and cooling behaviors of laminated glass facades exposed to fire, there is an urgent need to reduce the huge computational requirements associated with simulating heat transfer in layered structures that feature a down-flowing water film. We overcome this challenge by proposing, for the first time, an efficient three-dimensional finite difference method (3DFDM), which has high numerical stability when solving the heat transfer equations with water film and air convection. To capture the moving particles of the water film, we developed a unique computational algorithm for particle labelling, which has two significant advantages: (1) it eliminates the time-consuming process of searching for neighboring particles in conventional meshfree methods, and (2) it ensures that every main particle interacts only with limited neighboring particles without utilizing any weights, thus significantly reducing the computational effort. We validated our proposed 3DFDM through experiments in heating and cooling scenarios and compared its thermal results with those obtained from the commercial software packages to demonstrate its high efficiency and accuracy. Furthermore, we examined the feasibility of our model in evaluating the effects of thickness of the interlayer (PVB layer) and water film release time on the cooling behavior of laminated glass during a fire.
