Melting rheology in thermally stratified graphene-mineral oil reservoir (third-grade nanofluid) with slip condition

Abstract More effective and lengthy energy storage systems have been highly desired by researchers. Waste heat recovery, renewable energy, combined heating power reactors all utilize technologies. There are three techniques that more for storing thermal energy: Latent is one type of storage, along with sensible chemical storage. far efficient affordable these methods. A method in a substance melting. The frozen to release the it had storing. ground-based pump’s exchanger coils around soil freezing, tundra melting, magma solidification, semiconducting processes examples melting phenomenon. Due above importance, present study scrutinizes behavior third-grade nanofluid stagnation point deformed Riga plate. plate, an electromagnetic actuator, made up alternating electrodes permanent magnet positioned on flat surface. Graphene nanoparticles put base fluid (Mineral oil) make homogenous mixture. Mathematical modeling acquired presence phenomenon, quadratic stratification, viscous dissipation, slippage velocity. Suitable transformations utilized get non-linear system ODEs. remedy temperature velocity via homotopic approach.
