摘要：

In this study, convective stability of nanofluid flow in an inclined porous channel is being numerically investigated. The effects of Brownian motion and thermophoresis are accounted for in the nanofluid model. In addition, the flow in the porous region governs Brinkman's equation. A normal mode analysis is used to get the eigenvalue problem for the perturbed state, which is then solved using the Chebyshev spectral collocation approach. The influence of various governing parameters, the critical Rayleigh number, and associated wavenumber are graphically displayed.
