In this study effect of radiation on the viscoelastic Walter-B fluid is investigated with heat sink/source. Sakiadis, Blasius, and stagnation point flows are considered at constant surface temperature. Some suitable similarity variables have been utilized to transform governing equations into ODE. An iterative approach based on the Legendre wavelet spectral collocation method is applied for the solution of the resulting equations. The obtained results are validated by plotting the residual error curves in each case. Temperature and heat transfer rate at wall are analyzed to investigate the influence of involved parameters. It is found that the Legendre wavelet spectral collocation method is very efficient and can be employed for the solutions of various non-Newtonian flow problems.
