radial flow acceleration is generated with strong blowing (fw>0). The swirling flow mobilized by the disk rotation acts as a pump drawing fluid inward which spreads radially outwards over the disk face... disk. It is known that the deformation of the disk is along the radial direction. In addition to that Stefan blowing is considered. The Buongiorno nanofluid model is taken care of assuming the fluid......
