Abstract The importance of heat transfer in nanoliquids cannot avoided because it playing crucial role the applied research fields. potential area applications included but restricted to thermal, biomedical, mechanical and chemical engineering. Therefore, is need time introduce new efficient way enhance transport rate common fluids. major aim this develop a BHNF (Biohybrid Nanofluid Model) model channel having expanding/contracting walls up Newtonian regimes blood. two sort nanomaterials (Graphene + CuO) along with blood as base solvent are taken for formation working fluid. After that, analyzed via VIM (Variational Iteration Method) examine influence involved physical parameters on behavior bionanofluids. results revealed that bionanofluids velocity rises towards lower upper end when range 0.1–1.6 (expanding case) $$- \, 0.1$$ - 0.1 $$1.6$$ 1.6 (contraction case). fluid attained high neighboring center portion channel. By increasing permeability ( $${A}_{1}=\text{0.1,0.2,0.3,0.4}$$ A 1 = 0.1,0.2,0.3,0.4 ), movement can be reduced optimum decrement observed about $$\eta =0.0$$ η 0.0 .
