A decoupled wavelet approach for multiple physical flow fields of binary nanofluid in double-diffusive convection

作者:

Highlights:

• Buongiorno’s nanofluids model is perfected in the presence of Dufour and Soret effects incorporating linear and nonlinear diffusiophoresis effects.

• All kinds of linear thermal boundaries are successfully formulated by interpolated Coiflet-type wavelet including Dirichlet, Neumann and Robin types.

• An efficient wavelet approach for highly nonlinear complex flow fields has been presented.

• Highly accurate wavelet solutions are obtained for larger range of physical parameters which are difficult given by traditional numerical methods.
