The numerical analysis is performed considering Cauchy number (Ca between 10−7 and 5×10−5), 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. © 2023 The Author(s)EnglishAll Open Access; Gold Open AccessHeat transferNanofluidicsPacked beds% reductionsCoupled interactionElasticHybrid nanofluidMagnetic-fieldNanofluidsPhase change processThermal changesThermal processTriangular vented cavityMagnetic fieldsArticle10.1016/j.csite.2023.103169
