Summary: This paper introduces a new stochastic nature-inspired optimization algorithm called Pelican Optimization Algorithm (POA) to solve optimization problems in various scientific disciplines. By simulating the natural behavior of pelicans during hunting, the POA demonstrates high performance in approaching optimal solutions for unimodal functions and exploring the main optimal area for multimodal functions. Comparison with eight well-known metaheuristic algorithms confirms the competitiveness of POA in providing optimal solutions for optimization problems.

Summary: This study numerically investigates the blood flow in a complex wavy curved channel in the presence of hybrid nanoparticles. The results reveal that the concentration of nanoparticles reduces the velocity of the blood and assists in the non-uniform channel core. Moreover, the volume fraction of nanoparticles and the dimensionless curvature of the channel decrease the temperature profile.
