Thermal and phase change process of nanofluid in a wavy PCM installed triangular elastic walled ventilated enclosure under magnetic field

Coupled interactions between magnetic field, wall elasticity and corrugation of the packed bed container on the phase change and thermal process are analyzed during nanofluid convection in a triangular shaped vented cavity. The numerical analysis is performed considering Cauchy number (Ca between 10-7 and 5 x 10-5), Hartmann number (Ha between 0 and 50), number of waves (N between 1 and 8) and nanoparticle solid volume fraction (SV-F between 0 and 2%). Higher values of Ca and Ha contributes positively to the phase change and thermal process. The reduction of phase transition time (TP) reduces by 23% at the highest Ca while heat transfer improvements of 22.8% are obtained. The optimum value of wave number is found as N = 2. The optimum configuration is found for elastic wall case at the parameters (50, 2, 2%). The heat transfer enhancement factor is found as 13.8 while the TP reduction is 5% as compared to worst case which is found at (Ha, N, SV-F) = (0, 8, 0) with rigid wall.

Automated summary

This study analyzes the coupled interactions between magnetic field, wall elasticity, and the corrugation of the packed bed container during nanofluid convection in a triangular shaped vented cavity. The numerical analysis considers the Cauchy number, Hartmann number, number of waves, and nanoparticle solid volume fraction. Higher Ca and Ha values have a positive impact on phase change and thermal process. The reduction in phase transition time and heat transfer improvements are observed. The optimum configuration is found for an elastic wall.
