Nanofluids and Nanoparticles Modeling and Simulation In our exploration of Nanofluids and Nanoparticles Modeling and Simulation, we investigate the complex dynamics of magnetized nanoliquids flowing along a radially stretching surface within a steady cylindrical coordinate system. This research involves the development of a comprehensive mathematical model that incorporates various complexities, including thermal radiation, viscous dissipation, heat source/sink effects, and variable chemical reactions.

Figure 2: Microfluidic device for bacterial inactivation. Microfluidics and Bacteria Inactivation

In our research on Microfluidics and Bacteria Inactivation, we utilize ANSYS Fluent for numerical simulations, incorporating User-Defined Functions (UDFs) to model complex phenomena. Specifically, we investigate the inactivation process of E. coli bacteria inside a germicidal chamber. This work involves the introduction of additional governing equations, such as the User-Defined Scalars (UDS), to capture bacterial behavior. Bacterial inactivation is modeled using the Arrhenius equation, which accounts for the impact of temperature on the inactivation rate. To visualize the physical model, microfluidic chambers are employed, where gold nanoparticles are incorporated and irradiated by lasers. Relevant Works:
