A set of governing equations is transformed into ordinary differential equations using the similarity transformation. The resulting equations are then solved using bvp4c solver in MATLAB. The effects of the wedge angle parameter  and nanoparticle volume fraction parameter of Al 2 O 3 − Cu/water on the skin friction coefficient and heat transfer characteristics are investigated. It is found that increasing the wedge angle parameter  and Cu nanoparticles volume fraction gives rise to the skin friction coefficient and heat transfer on the surface. Further, dual solutions exist when the wedge moves in the opposite direction with the free stream. Keywords: Hybrid nanofluid; nanoparticles; moving wedge; numerical solutions; dual solutions 1. Introduction Nanotechnology is a technology that has captured the attention of an abundant number of researchers since the last century. In 1959, nanotechnology was first introduced by Nobel Laureate Richard P. Feynman, an American physicist during his lecture “There’s Plenty of Room at the Bottom”. Since then, nanotechnology has been widely used in the industry as it provides cleaner and more efficient energy supplies, which may help decrease construction, maintenance, repair, and decommissioning activities [1,2]. Nanofluids are a technology that falls under nanotechnology. Nanofluids were first proposed by Choi and Eastman [3]. A nanofluid can be categorized as a group of base fluids that consists of nanometer-sized particles (1-100 nm) [4]. The nanoparticles were usually made of metals, oxides, carbides, nitrides, or nonmetals. Nanofluids are produced by dispersing the nano-sized particles into * Corresponding author.
