Analysis of magnetohydrodynamic laminar boundary layer flow, heat, and mass transfer of nanofluids on a moving surface with thermal radiation via Bernoulli wavelets technique

Abstract

This study investigates the nanofluid’s magnetohydrodynamic boundary layer flow (BLF) in the presence of thermal radiation using the Bernoulli wavelet collocation method (BWCM). The governing nonlinear partial differential equations (PDEs) are transformed into nonlinear coupled ordinary differential equations (ODEs) using the appropriate similarity transformations. The obtained ODEs are then transformed into a nonlinear system of algebraic equations using BWCM. By contrasting the BWCM with the NDSolve Mathematica command and the Haar wavelet method, the BWCM's validity is examined. The influence of the physical parameters on temperature, concentration, velocity, mass, and heat transfer rates are discussed through tables and graphs. It was found that the Prandtl number, thermophoresis parameter, Brownian motion parameter, radiation parameter, and Lewis number do not influence the skin friction coefficient.
