The squeeze film reaction between parallel annular disks is fully theoretically treated in this research using a non-Newtonian Rabinowitsch fluid model enhanced by nanoparticle influences. The Chelyshkov Wavelet Operational Matrix Method (CWOMM) provides a quick and precise computer method for solving the governing equations. The Krieger – Dougherty model, which represents the exponential dependency of viscosity on particle volume fraction, is used to realistically account for the concentration-dependent viscosity of nanofluids. According to the results, shear-thinning (pseudoplastic) behaviour results in a decrease in performance when compared to Newtonian liquids, whereas shear-thickening behaviour introduces a larger load-carrying capacity and longer response times. Numerous parametric studies highlight how nonlinear rheological factors and geometry configurations affect film dynamics and pressure distribution. This data aids in the development of novel, cutting-edge lubrication systems based on non-Newtonian fluid enhanced by nanoparticles.
