Abstract The exploration of blood‐based ternary nanofluid flow (Au, TiO₂, Ag) through a permeable stenosed artery with spatially dependent heat sink source is pivotal for advancing biomedical and engineering innovations such as hyperthermia treatments, drug delivery systems, external cooling simulations, thermal ablation, targeted therapies. This study focuses on the dynamics novel comprising Au, Ag nanoparticles, modeled Carreau fluid within geometry artery. effects magnetization spatial sources are analyzed to investigate velocity temperature profiles. A temperature‐dependent conductivity model employed better understand transport in arteries. spectral relaxation method (SRM) utilized derive numerical solutions, validated against well‐established bvp4c scheme. Among nanoparticles studied, Au demonstrates highest enhancement due its superior conductivity. Notably, increasing radiation parameter values (0.72, 1.2, 1.5, 1.7), improves by 9%, 7%, 6%, respectively.
