摘要

本论文的目的是研究在具有注入/吸入效应的达西-福克海默(Darcy-Forchheimer)多孔介质中,卡森-卡劳(Casson-Carreau)混合纳米流体在散热/源、磁场、热辐射和滑移条件影响下的磁流体流动和传热特性。所研究的混合纳米流体包括非牛顿流体的流变作用,并采用卡松-卡勒乌流体范式,将水视为基液,而氧化铝和铜则作为混合纳米粒子。在该模型中,卡逊-卡劳混合纳米流体的公式化被用于表达边界层问题。得到的微分方程通过非相似变换进行转换,然后进行数值求解。两种卡森-卡劳模型中的一些研究结果都影响了热辐射和吹气/吸气参数的热量传递。此外,皮肤摩擦系数在热辐射时表现相同,但在吸气/喷射参数状态下表现相反。

2D Radiative Casson-Carreau Hybrid Nanofluid Flow through a Circular Cylinder in a Darcy-Forchheimer Porous Medium
The impulse back the sitting treatise is to study the properties of magnetohydrodynamic flow and heat transfer for Casson-Carreau hybrid nanofluid under the effects of heat sink/source, magnetic field, thermal radiation and slip conditions in a Darcy-Forchheimer porous medium with injection/suction effect. The examined hybrid nanofluid includes rheological action of non-Newtonian and pursues fluid paradigm of Casson-Carreau considering water as a base fluid, whereas Aluminium oxide and Copper as a hybrid nanoparticles. In this model, the formularization of the Casson-Carreau hybrid nanofluid has been used for expressing boundary layer problem. The obtained differential equations are switched by using non-similar transformations and then solved numerically. Some of the outcomes of the examination in both Casson-Carreau models influence the upsurging transfer of heat by thermal radiation and blowing/suction parameters. Moreover, skin friction coefficient display identical behaviour for thermal radiation, but the opposite behaviour is noticed in the state of the suction/injection parameter.
