“…Vyas and his coauthors 32‐36 examined entropy production in various thermofluidic configurations, which included Casson fluid, micropolar fluid, second‐order fluid, forced convection, temperature‐dependent convection coefficient, and so on, in Darcy and Darcy–Brinkman models. Here, it is recalled that the internal structure of the porous matrix differs from medium to medium and is found in form of interconnected voids, network of capillaries, cracks, and so on.…”
