WebThe phenomena of diffusion-thermo or Dufour effect is defined as phenomena when a chemical system undergoes a concentration gradient to produce heat flux. Thermal diffusion plays a vital role in the phenomena tough have a small impact that can be very vital when applied on the species with differing molecular weights. WebJun 30, 2024 · This paper is concerned with the 2D magneto-micropolar equations with linear velocity damping and partial magnetic diffusion. We first examine that this system possesses a unique global smooth solution when the initial data is small. Moreover, we also study on the large-time behavior of these smooth solutions of the system.
