Latent Heat Phase Change Heat Transfer of a Nanoliquid with Nano–Encapsulated Phase Change Materials in a Wavy-Wall Enclosure with an Active Rotating Cylinder

A Nano-Encapsulated Phase-Change Material (NEPCM) suspension is made of nanoparticles containing a Phase Change in their core and dispersed fluid. These particles can contribute to thermal energy storage heat transfer by latent phase change as moving with the host Thus, such novel nanoliquids are promising for applications waste recovery systems. In present research, mixed convection NEPCM suspensions was addressed wavy wall cavity rotating solid cylinder. As move liquid, they undergo heat. The considered temperature-dependent capacity. governing equations mass, momentum, conservation were presented partial differential equations. Then, converted non-dimensional form generalize solution, solved finite element method. influence control parameters volume concentration nanoparticles, fusion temperature Stefan number, undulations well cylinder size, angular rotation, conductivities on enclosure. undulation number induces remarkable Nusselt number. There optimum temperatures which could maximize rate. increase (a decline number) boosts advantage employing particles.
