This research zeroes in on improving the freezing process by synergistically employing a wavy wall and fins. To enhance cold penetration, phase change material (PCM) is enriched with nanoparticles, single-phase model adopted due to low nanoparticle concentration. The numerical simulations leverage Galerkin method validation procedure affirms precision of code, extensively evaluating impacts ϕ (concentration additives) dp (particle diameter). With an increase particle diameter (dp), there initial 19.76% decrease required time, succeeded subsequent 50.56% when = 0.04. Furthermore, escalation results 11.04%, 40.91%, 26.36% reduction completion time for values 50, 40, 30 nm, respectively. Without inclusion powders, solidification lasts 84.8 s. However, introduction optimal powder size, this duration significantly reduces 50.1 emphasizes efficiency improvements attained through strategic integration wall, fins, PCM infused nanoparticles.
