Abstract
The effect of thermal radiation, heat generation, suction/injection, nanoparticles
type, and nanoparticle volume fraction on heat transfer characteristics and the
mechanical properties of unsteady moving cylinder embedded into cooling medi-
um consist of water with Cu, Ag, or Al2O3 particles are studied. The governing
time dependent boundary layer equations are transformed to ordinary differential
equations containing unsteadiness parameter, thermal radiation parameter, heat
source parameter, suction/injection parameter, curvature parameter, nanoparti-
cle volume fraction, and Prandtl number. These equations are solved numerical-
ly. The velocity and temperature profiles within the boundary layer are plotted
and discussed in details for various values of the different parameters. Also the
effects of the cooling medium and the external thermal forces on the mechanical
properties of the cylinder are investigated.
