Abstract

Mathematically study mass transfer phenomena involving chemical reactions in the flow of Sisko Ferro nanofluids through the porous surface. Three ferronano particles, manganese-zinc ferrite (Mn1/2Zn1/2FeO), cobalt ferrite (CoFeO), and nickel-zinc ferrite (Ni-Zn FeO) are considered with water (HO) and ethylene glycol (CHO) as base liquids. Appropriate resemblance transitions are used to convert the governing system of a nonlinear PDE to a linear ODE. The Runge-Kutta method, as extended by the shooting technique, is used to accomplish the reduction governing equations. The effects of various associated parameters on fluid concentration and mass transfer rate are investigated: magnetic criterion (M), Siskofluid material factor (A), Solid volume fraction (ϕ) for nanofluids, permeability parameter (Rp), Chemical reaction criterion (γ), Brownian motion factor (Nb), and Thermophoretic parameters (Nt). The current findings indicate that the diffusion proportion of Sisko Ferronanofluid Ni-Zn FeO-HO and CoFeO-HO is higher than that of Ni-Zn FeO-CHO and CoFeO-CHO respectively but it is opposite in the case of Mn-Zn ferrite. The comparison study was carried out to validate the precision of the findings.

摘要

对 Sisko Ferro 纳米流体在多孔表面流动中涉及化学反应的传质现象进行数学研究。考虑了三种铁纳米粒子,即锰锌铁氧体(Mn1/2Zn1/2FeO)、钴铁氧体(CoFeO)和镍锌铁氧体(Ni-Zn FeO),以水(HO)和乙二醇(CHO)为基液。适当的相似转换用于将非线性偏微分方程组转换为线性常微分方程组。采用扩展的龙格-库塔法和打靶技术来完成控制方程的简化。研究了各种相关参数对流体浓度和传质速率的影响:磁场准则(M)、Sisko 流体力系数(A)、纳米流体的固相体积分数(ϕ)、渗透率参数(Rp)、化学反应准则(γ)、布朗运动系数(Nb)和热泳参数(Nt)。研究结果表明,Sisko Ferronanofluid Ni-Zn FeO-HO 和 CoFeO-HO 的扩散比例高于 Ni-Zn FeO-CHO 和 CoFeO-CHO,而 Mn-Zn 铁氧体则相反。进行了比较研究以验证结果的精度。
