Abstract
An investigation has been conducted on the convective heat transfer and the entropy
production attributable to the presence of an infinitely long cylinder in a viscous fluid
exhibiting oscillatory motion. The heat transfer analysis is carried out by assuming that the
surface of the cylinder is isothermal. The entropy generation is caused by heat transfer
attributable to the finite temperature difference MT and viscous effects produced in the fluid.
The number of independent variables in the governing equations is reduced by using a proper
set of similarity variables. To obtain the solution of the nonlinear partial differential equation,
we use a well-known finite difference scheme by transforming the semi-infinite domain to a
finite domain. The numerical results have been analyzed by means of a comprehensive
parametric study. It is observed that the entropy production intensifies in the presence of the
oscillatory motion of the cylinder.
