The present numerical investigation aims to analysis the enhancement heat transfer in nanofluid filled-complex geometries saturated with a partially layered porous medium. vertical walls of cavity are taken as complex wavy geometries. horizontal flat insulated temperature. is filled and upper half In analysis, governing equations formulated for natural convection under Boussinesq approximation ...

We present an exponentially convergent semi-implicit meshless algorithm for the solution of Navier-Stokes equations in complex domains. The discretizes partial derivatives at scattered points using radial basis functions (RBF) as interpolants. Higher-order polynomials are appended to polyharmonic splines (PHS-RBF) and a collocation method is used derive interpolation coefficients. interpolating...
