Re and Pr are defined as follows: The mean Brownian velocity

u B is given by: Here, k b is the Boltzmann’s constant. Following Corcione [14], the viscosity of nanofluid is given as follows: (11) Here, d f is the diameter of base fluid molecule, M is the molecular weight of Fludarabine molecular weight the base fluid, N is the Avogadro number, and ρ fo is the mass density of the base fluid calculated at the reference temperature. In this model, it is assumed that the vertical plate is at uniform temperature (T w  ’), and the lower end of the plate is at ambient temperature (T ∞  ’). Therefore, the initial and boundary GDC-0994 clinical trial conditions for the flow are as follows: (12) To simplify Equations 1, 2, and 3 along with the boundary conditions (Equation 12), following nondimensional quantities are introduced. (13) Therefore, the transformed equations are as follows: (14) (15) or (16) The function Adriamycin nmr A(θ) can be found using Equations 9 and 10. The nondimensional constants, Eckert number (Ec), Rayleigh number (Ra), Forchheimer’s coefficient (Fr), and Darcy number (Da) are given as follows: The other nondimensional coefficients appeared in Equations 15 and 16 and are given as follows: The corresponding initial and boundary conditions in nondimensional form are as follows: (17) The quantities of physical interest, such as the local

Nusselt number, average Nusselt number, local skin friction coefficient, and average skin friction coefficients are given as follows: Local Nusselt number: Introducing nondimensional parameters defined in Equation 13, we get the following: (18) Similarly, the average Nusselt number in nondimensional form is as follows: (19) The local skin friction coefficient

in nondimensional form is as follows: (20) Average skin friction coefficient in non dimensional form: (21) Method of solution In order to solve the nonlinear coupled partial differential equations (Equations 14, 15, and 16) along with the initial and boundary conditions (Equation 17), an implicit finite difference scheme for a three-dimensional mesh is used. The finite difference equations corresponding ADAM7 to these equations are as follows: (22) (23) (24) Equations 23 and 24 can be written in the following form: (25) Here, A i , B i , C i , D i , and E i (i = 1, 2) in Equation 25 are constants for a particular value of n. The subscript i denotes the grid point along the x direction, j along the y direction, and n along the time (t) direction. The grid point (x, y, t) are given by (iΔx, jΔy, nΔt). In the considered region, x varies from 0 to 1 and y varies from 0 to y max. The value of y max is 1.0, which lies very well outside the momentum and thermal boundary layers. Initially, at t = 0, all the values of u, v, and T are known. During any one time step, the values of u and v are known at previous time level.
