It is found that the steady-state solution is reached after time t_s = 8.5. It is also observed that due to greater viscous dissipative heat or the presence of radiation, there is a rise in the skin friction and a fall in the Nusselt number.</p> https://www.ultrascientist.org/paper/1207/ Numerical Solution Transient Free Convective Vertical Porous
