AB - In this study, we investigate the heat transfer characteristics in unsteady  boundary layer flow of Maxwell fluid by using Cattaneo-Christov heat flux  model and convective boundary conditions. The flow is caused by a sheet  which is stretched periodically back and forth in its own plane. The  physical model that takes into account the effects of constant applied  magnetic field is transformed into highly nonlinear partial differential  equations under boundary layer approximations. The solution of dimensionless  version of these equations is developed using homotopy analysis method. The  simulations are presented in the form of temperature and velocity profiles  for suitable range of physical parameters. The obtained results illustrate  that an increase in Deborah number and Hartmann number suppress the velocity  profiles. It is further observed that Cattaneo-Christov heat flux model  predicts the suppression of thermal boundary layer thickness as compared to  Fourier law.
