Fig. 5
Shows a comparative response between the numerical NS of Eq. (21) and the approximate solution NPA from Eq. (29). The non-dimensional parameters that were held constant are: \(B = 0.09,\,\rho_{3} = 3,\,\rho_{1} = 1,\mu_{1} = 1,\mu_{3} = 2,\)\(A = 0.07,\) \(D_{n} = 0.5,\varepsilon_{1} = {0}.002,\varepsilon_{3} = {0}.005,\)\(P_{e} = 25,.\beta_{c} = 2{,}\,a = 1.6,\)\(E_{0} = 0.5,\,\,k = 1.15,\,\,B_{d} = 0.005{,}\,\,{\text{and}}\,Oh = 0.022.\)
