Abstract: This investigation enlightens the hydrothermal features of chemically reactive nanofluidic transport over an inclined spinning disk. The revolving disk is considered to move freely with uniform angular velocity. The surface of the disk is permeable. The nanofluid flow is considered thermally radiative. Also, the presence of a heat source/sink is included to portray a more realistic outcome. How the permeability feature of the surface affects the hydrothermal integrity has been analyzed in detail. The prime dimensional equations are made dimensionless using appropriate similarity transformation. After then, the spectral quasi linearization method (SQLM) is operated to solve those equations. Residual plots are extracted to exhibit the speediness of the introduced SQLM technique. Several graphs, three-dimensional figures, and tables are rendered to avail the consequences of the underlying parameters. The linear regression slope procedure is included to quantify the enhancement or reduction of the heat and mass transport as well as shear stresses. The outcomes assured that the normalized thickness parameter augments the radial velocity and nanoparticle concentration. Chemical reaction reduces the concentration profile for suction but amplifies for injection. The temperature drops off for suction, while it amplifies for injection. Heat transport drops off for heat source, but heat sink conveys the reverse scenario. Heat source drops down the heat transference at the rate of 0.69874 for injection and 0.8374 for suction. Mass transport amplifies for chemical reaction during injection, while the reverse trend is detected for suction. This investigation has noteworthy applications in the mechanical and chemical engineering process.
