Abstract
Abstract Many researchers and scientists are devoting their time to scrutinize nanofluids nature and characteristics for heat transfer enhancement. The scrutiny of nanoliquids is important in the large scale thermal management systems via evaporators, advanced cooling systems, heat exchangers, micro/nano-electromechanical devices and industrial chilling applications. Nanoliquids are very momentous even in the natural process via different fields like chemistry, chemical engineering, physics and biology. Nanoliquids can be utilized in various fields of engineering such as different chemical procedures, cooling of electronic equipment and heat exchangers. The main aim of current article is to scrutinize electromagnetohydrodynamic flow of micropolar-Casson-Carreau nanoliquids over thin needle with Robinson’s conditions and Arrhenius pre-exponential factor law. Double stratification effects are also taken into account. The reverent partial differential equations are reformulated into the system of ordinary differential expressions by implementing appropriate transformations. Such obtained equations subject to boundary constraints are computed numerically by considering Runge–Kutta-Fehlberg method. Behaviour of numerous interesting parameters on flow fields is deliberated. The outcomes of flow fields are delineated through graphs and tabular data.
