摘要: Abstract The paper investigates the thermal stability of a horizontal layer Newtonian nanofluid in linear and non-linear regimes. A finite depth fluid is considered which incorporates effect Brownian motion thermophoresis slip mechanism along with no nanoparticle flux boundary conditions. For normal mode analysis performed whereas two term Fourier series has been used for nonlinear analysis. In case stability, analytic expression Rayleigh number (Ra) terms various pertinent parameters are obtained. graphs presented to visualize these on critical value (Racr). Thermal Nusselt also plotted discussed.
