The unsteady magnetohydrodynamic (MHD) flow on a horizontal preamble surface with hybrid nanoparticles in the presence of the first order velocity and thermal slip conditions are investigated. Alumina (Al 2 O 3 ) and copper (Cu) are considered as hybrid nanoparticles that have been dispersed in water in order to make hybrid nanofluid (Cu À Al 2 O 3 /water). The system of similarity equations is derived from the system of partial differential equations (PDEs) by using variables of similarity,

Further, it is examined that layer separation is deferred due to the effect of the hybrid nanoparticles. Moreover, the capacity of the thermal enhancement of Cu À Al 2 O 3 /water hybrid nanofluid is higher as compared to Al 2 O 3 /water based nanofluid and enhancements in Cu are caused to rise the fluid temperature in both solutions. In the last, solutions stability analyzes were also carried out and the first solution was found to be stable.
