Abstract:The finite element method is employed to solve the temperature-dependent problems of underground cable systems under pressure and/or electric fields. The temperature-dependent solutions have a large effect on the secondary flow and Nusselt number. However, it has only a minor effect on axial velocity and friction factor.
The effects of various parameters upon the EHD pumping operation have been studied in this work. The ground potential at the center of the pipe can be obtained by either increasing the radius of the pipe or decreasing the wavelength. It is not necessary to put the ground wire in the center of the pipe and, consequently, additional friction loss of the flow can be avoided. Higher voltage will raise the flow rate. Rayleigh numbers have a minor effect upon the flow rate. This implies that the small temperature differences in the fluid are enough to drag the fluid.
