A mathematical model of micropolar squeezing flow of nanofluids between parallel planes is taken into consideration under the influence of the effective Prandtl number using ethyl glycol (C2H6O2) and water (H2O) as base fluids along with nanoparticles of gamma alumina (&gamma:Al2O3). The governing nonlinear PDEs are changed into a system of ODEs via suitable transformations. The RKF (Range&ndash:Kutta&ndash:Fehlberg) technique is used to solve the system of nonlinear equations deriving from the governing equation. The velocity, temperature, and concentration profiles are depicted graphically for emerging parameters such as Hartmann number M, micronation parameter K, squeeze number R, Brownian motion parameter Nb, and thermophoresis parameter Nt. However, physical parameters such as skin friction coefficient, Nusselt number, and Sherwood number are portrayed in tabulated form. The inclusion of the effective Prandtl number model indicated that the effect of the micropolar parameter K on angular velocity h(&xi:) in both suction and injection cases is opposite for both nanofluids. It is observed that the increase in angular velocity is rapid for &gamma:Al2O3&minus:C2H6O2 throughout the study.
