| description | This study examines the impact of a magnetic field and thermal radiation on the flow, heat transfer and mass transfer of an incompressible Casson fluid over a three-dimensional exponentially stretching sheet. The governing equations, including the continuity, momentum, energy and concentration equations, are formulated while incorporating the effects of the applied magnetic field, radiative heat transfer and the Casson fluid model. To facilitate numerical analysis, similarity transformations are employed to non-dimensionalize the system. A coordinate transformation is introduced to convert the semi-infinite domain [Formula: see text] into a finite domain [Formula: see text] aligning with the applicability of the numerical wavelet method in a finite interval. The transformed equations are then solved numerically using the Bernoulli wavelet method, offering an efficient and accurate approach to addressing complex boundary layer problems. The validity of the results is confirmed through comparison with existing literature, demonstrating strong agreement. The effects of key parameters, including the Casson fluid parameter, magnetic field strength, radiation parameter and stretching rate, are analysed in terms of velocity, temperature and concentration distributions. The findings reveal that an increasing magnetic field suppresses velocity due to the Lorentz force, while thermal radiation enhances temperature distribution. Moreover, mass diffusion plays a crucial role in shaping concentration profiles. This study provides valuable insights into non-Newtonian fluid behaviour and highlights the effectiveness of wavelet-based numerical techniques in solving boundary layer problems. |
