Irreversibility analysis of the radiative flow of cross fluid comprising three distinct nanoparticles across a stretching cylinder with chemical reactions

Abstract
This study investigates entropy development in a magnetohydrodynamic (MHD) flow of trihybrid nanofluid in a cross fluid, including convective, thermal radiation, and heat source-sink through a stretching cylinder. The liquid that is contained within the enclosure is carboxymethyl cellulose (\r\n) water with tri-hybrid nanoparticles \r\n and \r\n. Suitable self-similarity variables are utilized to convert the nonlinear differential systems into ordinary ones. This transformation is accomplished through the bvp4c on MATLAB software. The influence of various variables over the velocity, temperature, concentration, entropy production, Bejan number, skin friction, Nusselt number, and the Sherwood number are sketched and elaborated. It is observed that enhancement in the magnetic field (\r\n) and Weissenberg number (\r\n) reduce the velocity profile, whilst the temperature uplifts due to (\r\n) and (\r\n). Moreover, an increase in the curvature parameter increases the thermal profile. In addition, uplifting the \r\n number ultimately increases the skin friction by approximately 37.4% and heat transmission by 45.21%, whereas the Sherwood number up to 1.98%. Comparison with previously published material confirms the accuracy of the presented numerical computations and supports our current proposed model. In biomedical applications, magnetic and electromagnetic fields play a significant role in radiofrequency ablation (RFA), magnetic resonance imaging (MRI), cancer therapy, tumor therapy, and malaria infection. This theoretical investigation may be productive in biomedical engineering, particularly in cardiology, skin problems treatment, and removing malignancies from the uterus.
