Obstacles, Interfacial Forms, and Turbulence: A Numerical Analysis of Soil–Water Evaporation Across Different Interfaces

摘要: Exchange processes between a turbulent free flow and porous media are sensitive to the dynamics in both regimes, as well interface that separates them. Resolving these complex exchange across irregular interfaces is key understanding many natural engineered systems. With soil–water evaporation application of interest, coupled behavior regimes investigated numerically, considering interfacial forms obstacles. Interfacial obstacles will alter conditions at interface, creating structures either enhance or reduce rates based on their velocity mixing with main flow. To evaluate how change rates, isolated numerically. First, different speeds compared for flat surface. Second, obstacle varied height introduced effects develop have analyzed. The parameters this then investigated. Next, interaction obstacles, second introduced, separated by distance. Finally, shape modified create wave forms. Each shown adjacent surface which mass, momentum, energy interface. These changes rate locations where higher gradients more develop, but low limited occur.
