Abstract
The liquid film flow of a blood-based hybrid nanofluid, comprising carbon nanotubes (CNTs) with variable viscosity, through a stretcshing sheet has been investigated. CNTs have many applications, such as high electrical and thermal conductivity, 18% more elasticity than other commonly used nanoparticles, high tensile strength, low thermal expansion coefficient, and improved electron emission, making the present effort more valuable. In this model, a magnetic field perpendicular to the flow field is used. The governing equations are designed in the form of nonlinear partial differential equations. By using the similarity transformation, the dimensionless ordinary differential equations are depleted. The homotopy analysis method was adjusted to solve this problem. The behavior of the momentum and energy profiles versus several physical constraints was investigated. The results indicated that the use of CNTs in the carrier fluid was more effective due to its C-C bond. CNT nanofluids can be functionalized to achieve the desired properties, which can be utilized for a variety of applications by functionalization of non-covalent and covalent modification.
