摘要
The flow of Bingham nanofluids at the ingress section functioning as non-Newtonian nanofluids in cylindrical concentric rollers have been studied. This analysis could be advantageous for chemical processing industries and thermal processing intensified systems. The silver(Ag), copper(Cu), Aluminum oxide(Al2O3) and Titanium dioxide(TiO2) nanofluids through water adjoining with Bingham fluid, which are refered as Bingham nanofluids with the yield value Bnf = 10. The investigative study had been carried out with the supposition that the cylindrical roller twain are revolving, with two different flow region space K = 0.3 and 0.8, in the selfsame along with the reverse directions including diverse angular velocity. Theoretically, this intensified system can be considered as an aircraft turbojet engine model. The continuity, momentum and energy equations were derived through the finite difference method. These equations were solved to find the pressure along the radial direction and to obtain velocity components such as axial, radial, tangential and thermal conductivity. Numerous nonNewtonian flow parameters, various concentrations with algebraic considerations were computed and results were obtained for the same. The major purpose of the present investigation is to identify the advancement of the velocities, pressure and thermal conductivity in the ingress section of considered processing intensified systems.
