The set of highly non-linear ordinary differential Equations (14)-(16) with boundary conditions (17)-(18) are solved numerically for the different scale of values of physical emerging parameters such as magnetic field parameter M, electric field [E.sub.1], porosity parameter [lambda], non-linear shrinking sheet parameter n, thermal radiation Rd, Eckert number Ec, Prandtl number Pr, Brownian motion parameter Nb, thermophoresis parameter Nt, Lewis number Le, Velocity slip [delta] and suction parameter s.
where [[sigma].sub.k] is the Prandtl number of turbulent kinetic energy, [[epsilon].sub.a] the turbulent dissipation rate of air, and [k.sub.a] the turbulent kinetic energy of air.
Where M = [[sigma][beta]0]/a is the magnetic field parameter, Pr = [vf]/[[mirco]]/[mu]f is the Prandtl number, [mathematical expression not reproducible] is the radiation parameter, [mathematical expression not reproducible] is the Grashof number and the corresponding boundary conditions are
The main fluid properties that are important to consider are the thermal conductivity ([k.sub.f]; W/m x K), the viscosity ([mu]; N x s/[m.sup.2]), Prandtl number (Pr), kinematic viscosity (v;[m.sup.2]/s) which can be obtained from Thermodynamic tables available in literature after linear regression as described through (6) to (9) for a temperature range of 100 [less than or equal to] T,(K) [less than or equal to] 550
[9], we will use the following parameter describing natural convection with low Prandtl number, that is, [alpha] = 5.
In these equations, Gk represent the generation of turbulence kinetic energy due to the mean velocity gradients, from [mu]t s2 where S is the modulus of the mean rate-of-strain tensor, [sigma]k and [sigma][member of] are the effective prandtl number for turbulent kinetic energy and rate of dissipation, respectively and pt is modeled as [mu]t=[rho]k2/[member of] (Ao+As (k[U.sup.*])/[member of])-[and]1 (11)
The unsteady nondimensional governing linear equations are solved by Laplace transform technique for the case of unit Prandtl number and unit Schmidt number.
Considering the fact that Prandtl number is strongly dependent on plastic dynamic viscosity and thermal conductivity, and it is assumed that both properties vary linearly with temperature; hence for more accurate analysis of boundary layer as suggested in [47, 48], the Pr in (14) is
