| چکیده | ||
| In this paper the Fourier Transform Combined with Adomian Decomposition Method (FTADM) is applied for solving the squeezed unsteady flow between the parallel plates influenced by an inclined magnetic field. By moving these plates towards each other, the squeezing flow which is perpendicular to the plates is appeared. We assume that inclination varies from 0 to 90 degrees. The momentum and energy equations are solved using the Fourier Transform Combined with Adomian Decomposition Method transform. The effect of the squeezed number, the angle of the magnetic inclination, and the bottom plate suction/injection on the velocity and temperature are studied. The results show that by increasing the squeeze number, the intensity of the magnetic field and the magnetic inclined angle may increase the velocity and bottom plates in the longitudinal direction. However, the velocity near the midway of up and bottom plates may decrease. Moreover, our results show more accuracy and a smaller number of calculations when compared to the previous numerical simulations. This may be attributed to the fact that in FTADM, one is able to incorporate all boundary conditions into the solution. However, in the semi-analytical methods, the solution may be accurate in a limited portion of the solution domain, since only a part of the boundary conditions is imposed into the solution. | ||
