The unsteady laminar boundary-layer flow and heat transfer of a viscous fluid over a
stretching cylinder is discussed in this work. To normalize the governing system of equations
a proper set of similarity variables is used. Two types of thermal boundary conditions,
prescribed surface temperature (PST) and prescribed heat flux (PHF), are taken into account
for thermal analysis. The governing equations are solved using the homotopy analysis
method, and the obtained series solution is found to be valid for the entire temporal and spatial
domains and for certain ranges of the other physical parameters. The effects of various
material parameters on different physical quantities, such as the coefficient of skin friction
and the Nusselt number, are illustrated through graphs and tables.
