The study of magnetohydrodynamic (MHD) flows, particularly those involving non-Newtonian fluids like the Oldroyd-B fluid, is pivotal in various industrial applications. These include chemical engineering, petroleum extraction, and material processing. Understanding the behavior of such fluids under different conditions can lead to enhanced efficiency and innovation in these fields.
Significance of the Oldroyd-B Fluid Model
The Oldroyd-B fluid model is a type of non-Newtonian fluid that accounts for both relaxation and retardation times, making it highly relevant for processes where viscoelastic properties are significant. This model helps in understanding complex flow behaviors that are not captured by simpler Newtonian models.

The research paper titled "Impact of heat generation/absorption of magnetohydrodynamics Oldroyd-B fluid impinging on an inclined stretching sheet with radiation" provides valuable insights into how heat generation and absorption affect MHD flows. The study uses numerical methods to solve transformed governing equations, revealing how parameters like the radiation parameter and Deborah number influence velocity and temperature profiles.
Key Findings
- An increase in the radiation parameter leads to a decrease in velocity but an increase in temperature profiles for opposing flows.
- The Deborah number significantly impacts velocity and momentum boundary layers, enhancing them as it increases.
- The heat transfer rate decreases with increased magnetic strength but improves with higher Prandtl and Deborah numbers.

These findings have profound implications for industries relying on precise control of fluid dynamics. For instance, in petroleum engineering, understanding these dynamics can improve the efficiency of crude oil extraction. Similarly, in chemical processing, optimizing heat transfer can lead to better energy management and product quality.
