| Abstract: | In this study, forced convective squeezing flow between two rotating parallel plates has been examined. The thermal conductivity depends on the distributions of the temperature and the flow, electric and magnetic fields are considered as time dependent. The worked suspension is ternary hybrid nanofluids which consist of water as a base fluid and graphene, Al2O3 and MWCNT as nanoparticles. The energy equation consists of viscous dissipation, radiation, and Joule heating terms. Suitable transformations are introduced as a first step of the solution methodology and fourth order differential equations are obtained. The resulting system is solved, numerically, and various validation tests are performed. The main outcomes revealed that profiles of the stream function are lower when the squeezing parameter, electric field parameter, or magnetic parameter increases. Also, there is an enhancement in values of the temperature gradients up to 16.78% at the lower plate when the Joule heating parameter is varied from 0 to 6. [ABSTRACT FROM AUTHOR] |
