According to the abstract released by the Intellectual Property India: "This invention presents a comprehensive mathematical model developed to analyze blood flow through arteries containing multiple stenoses under the influence of an externally imposed magnetic field. The model integrates principles of fluid mechanics, hemodynamics, and magnetohydrodynamics to capture the complex interactions between blood rheology, arterial narrowing, and electromagnetic forces. By treating blood as an electrically conductive fluid and incorporating the Lorentz force into the modified Navier-Stokes equations, the invention provides an accurate representation of how magnetic fields alter velocity distribution, pressure gradients, shear stress patterns, and flow disturbances within diseased arterial segments. The invention utilizes realistic geometric representations of multiple stenoses, allowing variations in shape, severity, and spacing to be precisely incorporated into the computational framework. Pulsatile boundary conditions reflecting the cardiac cycle further enhance the physiological relevance of the model, enabling detailed simulation of time-dependent flow behavior rather than relying on oversimplified steady-state assumptions. Through advanced numerical methods, the model generates high-resolution predictions of hemodynamic parameters essential for understanding the progression of atherosclerosis and related cardiovascular complications. A key advantage of the invention is its ability to account for the combined and nonlinear effects of multiple stenoses, which interact in ways that cannot be accurately predicted by single-stenosis models. The inclusion of magnetic field influence adds another dimension of analysis, offering valuable insights for applications such as magnetic drug targeting, MRI safety evaluation, and the development of electromagnetic medical devices. The invention thus serves as a versatile and powerful tool for researchers, clinicians, and biomedical engineers seeking to interpret complex arterial flow dynamics, optimize therapeutic strategies, and improve diagnostic accuracy. By unifying multiple physical phenomena within one modeling system, this invention establishes a novel and advanced approach to cardiovascular flow analysis."
