Numerical simulation of unsteady squeezing nanofluid and heat flow between two parallel plates using wavelets

In the present study, unsteady squeezing nano fluid flow between two parallel plates has been investigated first time with wavelets. Similarity transformation has been used to transform the governing nonlinear momentum and thermal energy equation to a nonlinear coupled ordinary differential equation with fitted boundary conditions. For nonlinear coupled ordinary differential equation we present the new perspective of Haar wavelet transform with essential idea of scale-3 Haar wavelets. The numerical investigation is carried out for various physical parameters such as squeeze number, Reynolds number, Eckert number and nano particle volume fraction. As a main outcome from the present study is that, wavelet yields more accurate results than the other numerical results that are available in the literature. We have used Haar wavelets with scale-2 and scale-3 parameters for dilation and it has been found that wavelets with scale-3 produces better results than scale-2 wavelets.
