In this paper, we discuss thin‐film nanofluid sprayed in
non‐Darcian, magnetohydrodynamic, embedding in a
porous medium flow and thermal radiation with heat
transfer generation on a stretching cylinder. The spray rate
is a function of film size. A comparative study is made for
the nanoparticles, namely, copper oxide (CuO), alumina
oxide (Al2O3), and iron oxide (Fe3O4). The governing
continuity, momentum, and energy equations of the
nanofluid are reduced using similarity transformation and
converted into a system of nonlinear ordinary differential
equations, which are solved numerically. Numerical
solutions are obtained for the velocity and temperature
fields as well as for the skin‐friction coefficient and Nusselt
number. The pressure distribution and spray rate are also
calculated. The results are presented in graphical forms to
study the effects of various parameters.
