Numerical simulation of squeezing Cu-Water nanofluid flow by a kernel-based method

The main aim of this paper is to propose a kernel-based method for solving the problem of squeezing Cu-Water nanofluid flow between parallel disks. Our method is based on Gaussian Hilbert-Schmidt SVD (HS-SVD), which gives an alternate basis for the data-dependent subspace of "native" Hilbert space without ever forming kernel matrix. The well-conditioning linear system is one of the critical advantages of using the alternate basis obtained from HS-SVD. Numerical simulations are performed to illustrate the efficiency and applicability of the proposed method in the sense of accuracy. Numerical results obtained by the proposed method are assessed by comparing available results in references. The results demonstrate that the proposed method can be recommended as a good option to study the squeezing nanofluid flow in engineering problems.
