Presently, NEPCMs (nanoencapsulated phase change materials) have received excessive consideration due to their capacity to release heat and absorb heat, taking it as flawless choice for applications in industry and various engineering fields. The present work is associated with the heat transfer performance of water-based NEPCMs nanofluid flow through a wedge surface under free convection condition. The nanoscale PCM capsules are formed by the n-nonadecane as a core and protective shell as a polyurethane. The impact of various operational parameters and geometrical parameter on surface drag force and heat transfer was investigated by using numerical method, i.e., bvp4c. These parameters comprise slip velocity, suction/injection, thermal radiation, magnetic field, viscous dissipation, volume fraction of NEPCMs, and wedge angle. The present code is validated with previous published literature under special case. The study reports that the heat transfer accelerated due to increase in volume fraction of NEPCMs nanoparticles from 2 to 6%. Fluid velocity escalated with increasing the values of suction and injection variables, while higher dissipation results in enhanced heat transfer. The study findings provide a valuable insight for application such as designing aircraft to improve boundary layer stability, optimizing heat extraction in underground thermal reservoir, and cooling of electronic devices.
