Abstract
The suspension of tiny solid particles inside the energy transport liquids could enhance their thermal conductivity as well as provide an efficient and inventive approach to significantly improve their properties of heat transport. Therefore, our aim is to explore the radiative two-dimensional unsteady flow of a viscous nanofluid about an aligned magnetic field that includes the joint effect of suction, velocity slip, and heat source across a porous convective stretching/shrinking surface. Initially, using non-dimensional variables, the nonlinear governing partial differential equations (PDEs) were transformed into ordinary differential equations (ODEs) which were subsequently solved with the help of bvp4c built-in package in MATLAB. The results declare that escalating the values of the unsteadiness parameter escalates the friction drag whereas it reduces with the escalation of the slip parameter. Furthermore, the heat transfer rate escalates with the escalation of radiation and concentration parameter, and the escalation of the heat source parameter causes to reduce the heat transfer rate. Finally, it is found that the rate of heat transfer and friction drag continuously improve and decline against the rising rates of stretching, respectively.

Summary
A substance that flows continuously during the exertion of an exterior force is called a fluid. The common categories of the fluids are real fluids, ideal fluids, Newtonian fluids, non-Newtonian fluids, and the ideal plastic fluids Newtonian fluids are those that satisfy Newton’s law of viscosity, called viscous fluids. Tamim et al [5] explored the mixed convection in a time-dependent stagnation point flow of a nano liquid across a porous vertical surface. Nadeem et al [8] explored the study of viscous nanofluid associated with stagnation point and magnetic field across a curved stretched surface. The comparative influence of different hybrid nanofluids on the heat and mass transport flow with the exterior aligned magnetic field was studied by Khan et al [9] across a stretched surface associated with thermal radiation.
