In this research, the radially increasing axisymmetric discharge of an
electrically conducting fluid across a surface is accurately evaluated
mathematically using the influence of Soret number. The surface is
extended at an exponential speed in a radial direction, which causes
flow trends. New similarity transformations are discussed in order to
transform the governing, transform nonlinear partial differential
equations into standard derivatives. The Successive Linearization Method
is used to perform mathematical analysis for flow performing. The
Chebyshev spectral technique is utilized to resolve the linear system in
order to provide accurate solutions that converge effectively to the
whole numerical solution. Comparisons with earlier research are
conducted to evaluate the validity of the results on the distribution of
velocity, temperature and concentration. Verify convergence and accuracy
of the solution, the impacts of a few fluid factors are identified and
explained.
