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://thegreensjunglebeautyshops.shop/product-category/mask-brush/
