We study natural convection from a downward pointing cone in a viscoelastic fluid embedded in a porous medium. The fluid
properties are numerically computed for different viscoelastic, porosity, Prandtl and Eckert numbers.The governing partial differential
equations are converted to a system of fourth order ordinary differential equations using the similarity transformations and
then solved together by using the successive linearizationmethod (SLM).Many studies have been carried out on natural convection
from a cone but they did not consider a cone embedded in a porous medium with linear surface temperature. The results in this
work are validated by the comparison with other authors.
