Abstract This article comprehensively examines the dynamics of pressure‐driven hydromagnetic flow Carreau–Yasuda nanofluid through an inclined porous channel, subjected to both linear and nonlinear thermal radiation. Additional factors, such as nonuniform heat source/sink, thermophoresis, Soret diffusion, Brownian motion, Joule heating, Beavers–Joseph slip condition, are also considered.
