We investigate entropy production rate in a temperature dependent viscosity Hartmann flow with Hall current through a rotating permeable channel. It is assumed that fluid suction occurs at the upper wall and injection at lower wall. The nonlinear governing differential equations are obtained, analyzed and solved numerically using shooting technique together with Runge-Kutta-Fehlberg integration method. Velocity and temperature profiles obtained from the numerical solutions are then used to compute the skin frictions, Nusselt number, the entropy generation rate and the Bejan number. The germane results are presented and discussed quantitatively.

The present analysis deals with the entropy analysis of the blood flow through an anisotropically tapered arteries under the suspension of magnetic Zinc-oxide (ZnO) nanoparticles (NPs). The Jeffrey fluid model is contemplated as blood that is electrically conducting and incompressible. The lubrication approach is used for the mathematical modeling. The second law of thermodynamics is used to examine the entropy generation. The exact solutions are obtained against velocity and temperature profile with the use of computational software. The results for Entropy, Velocity, Bejan number, temperature profile, and impedance profile are discussed by plotting the graphs. ZnO-NPs have promising applications in biomedical engineering due to its low toxicity, economically reliable, and excellent biocompatibility. ZnO-NPs also emerged in medicine i.e., antibacterial and anticancer activity, and also beneficial in antidiabetic treatment. The monitoring of the blood temperature in the case of the tapered artery has supreme importance in controlling the temperature of blood in the living environment. The presence of a magnetic field is advantageous to manage and control the blood motion at different temperatures. The present outcomes are enriched to give valuable information for the research scientists in the field biomedical science, who are looking to examine the blood flow with stenosis conditions and also beneficial in treating multiple diseases.
