The unsteady flow over a continuously shrinking surface with wall mass suction in a nanofluid using the model proposed by Buongiorno [7] is investigated. By using an appropriate similarity transformation, similarity equations are obtained and the shooting method is used to solve these equations for different values of the wall mass suction, unsteadiness and nanofluid parameters. It is found that dual solutions exist for a certain range of wall mass suction, unsteadiness and nanofluid parameters.
