The study investigates nanoparticles modeled using a Levenberg–Marquardt neural network (LM-NN).

The research methodology includes modeling blood flow as pulsatile within a parallel plate channel. It also incorporates porous media to simulate foamy structures. The study addresses heat transfer dynamics and chemically reactive species. It uses nanoparticle concentration equations that account for diffusion, convection, and chemical reaction processes. The study concludes that combining machine learning with fluid dynamics modeling greatly improves the understanding of drug delivery efficiency. It also highlights its impact on physiological factors. Heat transfer, Reynolds number, and parameters like Darcy and Forchheimer are vital for optimizing the delivery of therapeutic agents. Magnetic fields and Schmidt numbers are crucial for regulating blood flow and enhancing treatment outcomes. These insights could lead to improved treatment protocols and better management of blood flow within the cardiovascular system, particularly in areas targeted for cancer treatment.

HCFOs have emerged as promising candidates, both as pure fluids and in mixtures with HCs. These blends show efficiency and potential non-flammability for high-temperature applications, but experimental data on their thermophysical properties remain scarce. This study presents the first experimental measurements on the {n-pentane (R601) + trans-1-chloro-3,3,3-trifluoro-1-propene (R1233zd(E))} binary system. In particular, the compressed liquid density of three mixture compositions have been measured employing a vibrating tube densimeter within the temperature range from 283.15 K to 423.15 K and at pressures ranging from 1 MPa to 12 MPa. A novel technique was applied to ensure a combined uncertainty (k=2) not greater than 0.0003 mol(cdot)mol(^{-1}) in the mixture composition, leading to final combined uncertainty (k=2) on the liquid density of no more than 0.2%. Finally, a new mixture model based on the Helmholtz-energy-explicit Equation of State has been developed from such experimental data.
