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 non-Newtonian 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.

过程强化系统入口段非牛顿纳米流体流动分析

已经研究了宾汉纳米流体在圆柱同心辊中作为非牛顿纳米流体在入口部分的流动。这种分析可能有利于化学加工工业和热处理强化系统。银(Ag)、铜(Cu)、氧化铝(Al 2 O 3)和二氧化钛(TiO 2)纳米流体通过水与宾汉流体相邻,称为宾汉纳米流体,屈服值 B nf  = 10。研究假设圆柱滚子在旋转,具有两个不同的流动区域空间K = 0.3 和 0.8,在相同的方向上,包括不同的角速度。理论上,这种强化系统可以看作是飞机涡轮喷气发动机模型。通过有限差分法推导出连续性、动量和能量方程。求解这些方程以找到沿径向的压力并获得速度分量,例如轴向、径向、切向和热导率。计算了许多非牛顿流动参数,考虑了代数的各种浓度,并获得了相同的结果。本研究的主要目的是确定所考虑的加工强化系统的入口部分的速度、压力和热导率的进步。
