Summary:The present paper contains a study of heat transfer and flow of a power-law nanofluid in bent vertical wavy walls enclosure. The system of governing equations has been solved by mesh free method (EFGM) with a parallel scheme. The results are found in terms of heat transfer rate at the hot wall, isotherms and streamlines under the influence of Aspect ratio, Rayleigh number, Prandtl number, power-law index and wave amplitude. It is observed that the average Nusselt number improves with enhancing the Prandtl number, Rayleigh number and aspect ratio but it decrements with enhancing the power-law index and surface waviness. A parallel implementation scheme gives better efficiency as compared to the sequential scheme. Such problems have direct application in electronic devices, food processing industries, and biomedical applications.
