| Summary: | Abstract This paper focuses on the crucial aim of testing solution accuracy in scientific research. It compares an analytical solution of blood flow and experimental data, offering a statistical analysis to assess the efficacy of the proposed model. The variable pressure gradient through a two-dimensional stenosis cylindrical artery addresses a gap in previous works. Using a perturbation approach, analytical solutions for critical parameters such as the velocity, wall shear stress, pressure gradient, flow rate, temperature and the Nusselt number are obtained across various physical parameters. The statistical analysis of our model shows excellent agreement with existing experimental data, underscoring the reliability of our proposed approach. This study revealed increased wall shear stress with stenosis height and contrasting behaviour for the slip parameter. The temperature increases with increasing nanoparticle volume fraction and Prandtl number but decreases with increasing radiation. Furthermore, the Nusselt number increases with the Eckert number and decreases with the radiation parameter. This research contributes valuable insights into blood flow dynamics and the effects of various physical parameters, enhancing understanding and informing future studies in the field. |
