An exploration is sought for improved thermal transportation across an extending inclined sheet in the upper space to be influenced by periodic micro gravity g *(tau) = g(0)(1 + a cos(pi omega t)) and magnetic field B-0. The mixed convection induced by g-jitter effects is studied for the flow of two colloidal liquids; the alone micropolar nano fluid (copper/ water) and micropolar hybrid nano fluid (alumenia-copper/ water). The leading formulation in its transformed form as ordinary differential format is manipulated via finite-element discretization. A computational code is coded in Matlab script to assess the impacts of involved parameters on dynamic of fluid. The differentiated enhanced performance of hybrid naofluids is observed in this upper space g-jitter influenced flow. The fluid velocity is slowed against growing strength of Hartmann number, but it becomes faster against micropolar material quantity. Both velocity and temperature distribution for hybrid nanofluid flow attains higher values in comparison with those of alone mono-nanofluid. The fluctuation of skin-friction factor and heat flux gradient improves with larger inputs of amplitude of modulation.
