Inventor(s) include Dr. N. N. V. Sakuntala; Adilakshmi Bonda; V. Lakshmi Sailaja; and Dr. V. Mallipriya.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a computational dynamic system and method for controlling stochastic mixing behavior in non-Newtonian nanofluid streams using harmonically oscillatory surfaces. The system integrates fluid dynamic modeling, adaptive computational algorithms, and oscillatory surface actuation to enhance mixing efficiency, thermal transport, and flow stability. In one embodiment, harmonic oscillations are applied within a frequency range of 10-500 Hz and an amplitude range of 0.1-5 mm to generate controlled perturbations in nanofluid streams flowing at Reynolds numbers between 100 and 5000. The nanofluid may contain 0.1-5% volume concentration of metallic or ceramic nanoparticles dispersed in non-Newtonian base fluids. The oscillatory mechanism promotes chaotic advection, improves nanoparticle dispersion uniformity by up to 35%, and enhances heat transfer efficiency by approximately 20-40% compared to conventional passive mixing systems. Real-time sensing and predictive control mechanisms dynamically regulate oscillation parameters according to viscosity and flow conditions. The invention is applicable in thermal engineering, biomedical systems, microfluidics, chemical processing, and advanced manufacturing applications requiring efficient and adaptive nanofluid mixing control."
