Abstract The present case study on the inclined magnetohydrodynamic‐cross‐nanofluid through the porous wedge deals with engine oil with zinc oxide and molybdenum disulfide to analyze its functioning for several operations influenced by electro‐osmosis flow, variable conductivity, variable viscosity, heat source‐sink factor, variable viscosity, angled magnetic field and heat flux mechanism. To keep the fluid's temperature sustainable, nanoparticle characteristics are carefully scrutinized. Diverse implications of the volume fraction of the nanoparticles and on the hybrid fluid's double diffusivity are responsible for the fluid's stability during motion. In addition, the conduct of temperature is better suited for engine oil because of the presence of nanoparticles. The velocity generally declined against the Helmholtz–Smoluchowski velocity and the potential rise due to the opposing electric field factor. The radiation factor raises the temperature zone while the concentration rate decreases and the double diffusivity due to the relative importance of conduction heat transfer and thermal radiation. The concentration and temperature contours decrease when the heat source parameter increases, but the double‐diffusivity is enhanced when the heat sink factor increases. Electro‐osmotic flow is a typical approach in soil analysis, chemical analysis and microfluidic devices utilizing structures with high‐voltage surfaces and processing.
