Abstract
This research culminates the arterial blood flow analysis through distinct stenotic regions. Four different forms of stenotic regions are woven together in present study, i.e. triangular, trapezoidal, overlapping (w-shape) and composite formations. The four reviewed stenotic forma-tions are first time considered in such numerical analysis. The considered problem is modeled for an elliptical cross-sectional artery by means of cartesian coordinate system. The governing coupled Partial differential equations are decoded numerically over this elliptical cross-section by using free source CFD software Open-FOAM. A precisely refined and proper mesh is generated for each arte-rial stenotic segment. A high magnitude of flow profile with some minor disruptions is observed near the origin of stenotic sections of artery. Pressure profile also has high values near the sharp corners of stenotic regions. Some expected irregularities in the flow profile are observed near the origin of stenotic regions as it happens in most of the real-life stenosed artery blood flow problems. (c) 2023 THE AUTHORS.
