Viscoelastic Dusty Nanofluids containing Nanodiamond in a Rotating Porous Channel

The utilization of viscoelastic fluid is prevalent in various industries such as medical sector, food, petrochemical, and polymer due to its ability to reduce turbulent drag, exhibit elastic turbulence, and other notable characteristics. This aspect has consistently captured the attention of researchers. In the present study, the aim is to report the results associated with the Couette flow of viscoelastic rotating dusty nanofluids between rotating porous plates. Furthermore, in the present study, transformer oil is used as a base fluid, because to its numerous applications in power engineering and industrial sciences. Transformers are one of the crucial elements that requires high-level condition monitoring to ensure continuous power supply. Therefore, an effort is made to improve the critical features of the transformer oil by suspending nanodiamond and aluminum oxide nanoparticles, because the creation of transformer oil with desirable dielectric and thermal properties is in high demand due to its essential role in development. The governing equations for the above flow regime is modeled and formulated in terms of partial differential equations. A definite method (Poincare Light-Hill technique) is then used to solve the non-dimensional partial differential equations. The impact of different parameters on the temperature and velocity profiles are shown graphically. Nusselt number and Skin friction are computed and tabulated. The nanofluid velocity is observed to decline with raising suction parameter and magnetic field. It is noteworthy that the transformer oil’s heat transfer rate is improved by 27.58% for Al_2O_3 nanoparticles and 31.27% for nanodiamond particles, when the Al_2O_3 and nanodiamond nanoparticles volume fraction is raised from 0.01 to 0.04 . This study has a wide range of applications in industrial science and engineering. This study also provides that how the nanofluids are using as a cooling agent.
