The present study concerns the momentum and heat transfer characteristics of magnetohydrodynamic (MHD) dusty nanofluid flow over a permeable stretching/shrinking surface in the presence of a volume fraction of dust and nanoparticles with non-uniform heat source/sink. We consider 2 types of nanofluids. namely. TiO2-water and Al2O3-water. https://parisnaturalfoodes.shop/product-category/nipple-butter/
