Does polyurethane-phase change materials foam composite have thermal conductivity?

To investigate the thermal conductivity of the Polyurethane-Phase Change Materials foam composite, we propose a hierarchical multi-scale model utilizing Physics-Informed Neural Networks (PINNs). This model allows accurate prediction and analysis of the material’s thermal conductivity at both the meso-scale and macro-scale.

What is the thermal conductivity of PU foam?

The thermal conductivity of the PU foam plays a critical role in the PCM heat absorption and release when the temperature is within the phase transition temperature range. Thermal conductivity is 0.023 W/mK for standard PU foam. It was observed that the thermal conductivity values increased as expected when the MPCM loading % was increased.

Can neural networks predict thermal conductivity of Pu-PCM (polyurethane phase change material)?

The primary objective of this study is to develop a multi-scale model based on Physics-Informed Neural Networks (PINNs) that can accurately predict the thermal conductivity of PU-PCM (Polyurethane Phase Change Material).

Do Pu-PCM foams have thermal energy storage capacity?

While previous studies have primarily focused on synthesis methods and experimental investigations of the thermal energy storage capacity of PU-PCM foams, there has been limited exploration of their thermal evaluation across multiple scales, which hinders a comprehensive understanding of the material’s behavior and its complex system.

Is polyurethane foam a good insulating material?

Polyurethane foam is a popular insulating material in the cold energy storage industry because of its lightweight and low thermal conductivity. The porous structure of the foam has been demonstrated in several studies to be a cause of PCM leakage, which is a crucial disadvantage of PU foam-integrated PCM composite material [ 18 ].
