“…Flow and heat transfer inside thin films in the presence of internal and external pressure pulsations was investigated by Khaled and Vafai [2]. Thin film flow due to stretching phenomena has been discussed by a number of workers such as Wang and Pop [3], Liu and Anderson [4], Mahmood et al [5], Wang [6], Dandapat et al [7] and Anderson et al [8]. The stretching problems for steady and unsteady flows have been studied extensively in various aspects, such as for non-Newtonian fluids, MHD flows, porous plates, porous medium and heat transfer analysis.…”
