Nanomaterial engineering advancement is obtained due to the development of tri-hybrid nanofluid which provides enhanced thermal properties in comparison to the nanofluids and hybrid nanofluids. Moreover, the improved thermal properties are useful in several applications in cooling electronic devices, industries, and biomedical devices. The present analysis devotes the study of magnetized squeezing Boger-micropolar hybrid nanofluid between concentric disks. The main focus goes to the investigation of shape factor of the nanoparticles. The implementation of thermal properties likely thermal conductivity, viscosity, and electrical conductivity considering various shapes such as spherical, cylindrical, and platelet shape nanoparticles. The dimensional form of the governing equations are obtained for the utilization of suitable transformation rules and further, the set of differential equations are handled numerically. In particular traditional Runge-Kutta fourth order technique is presented combined with shooting method to get the unknown initial condition and then solved. The results are depicted for the significant effect of the factors involved in the flow phenomena and the important outcomes are deployed as; The squeezing motion inside concentric discs enables efficient thermal control systems in a variety of commercial and biomedical applications.
