In this article. we study the revised model of boundary-layer flow past a permeable stretching/shrinking sheet over the heated surface in a nanofluid with stability and regression analyses. The revised model refers to a physically more realistic approach. where the nanoparticle fraction can be controlled on the boundary in a similar way as for temperature on the boundary. https://www.bekindtopets.com/limited-time-Gorra-Raul-Tan-special-save/
