摘要

This study examines the Falkner–Skan boundary layer flow over a moving wedge containing a mixture of nano-encapsulated phase change material (NEPCM) nanofluids. As the NEPCM particles are transported by the base fluid, they encounter temperature gradients within the boundary layer. This causes them to undergo melting and solidification processes associated with latent heat absorption and release. The governing partial differential equations are transformed into a system of coupled nonlinear ordinary differential equations using similarity transformations and solved numerically via the shooting technique combined with the Runge–Kutta method. The analysis explores the effects of the wedge motion parameter ( \(-0.5 \le \lambda \le 1.2\) ), the wedge angle parameter ( \(0.05 \le m \le 0.5\) ), the NEPCM volume fraction ( \(0.0 \le \phi \le 0.05\) ), the Stefan number ( \(0.2 \le Ste \le 0.8\) ), and the dimensionless fusion temperature ( \(0.03 \le T_f \le 0.3\) ). Increasing the NEPCM concentration was found to broaden and elevate the phase transition region, thereby enhancing both the local Nu and skin friction coefficient. This enhancement in thermal and momentum transport is particularly significant near the critical value of the wedge velocity parameter.
