Wind-Tunnel Investigation of Mass Transfer from Soil Corrugations

摘要: Abstract Distribution of local mass-transfer coefficients over saturated corrugated surfaces was measured in a wind tunnel. Wavy (sinusoidal) were used to represent field corrugations (furrows). Visualization techniques, conjunction with wall-pressure distribution measurements, investigate the air flow pattern near wave surface.The rates from various locations on surface are intimately related structure inside furrows. The buildup high humidity vortices formed furrows tends reduce moisture transfer. These significantly more effective reducing evaporation loss bottom deeper as compared shallower ones. This substantiates that furrows, if deep enough, can markedly decrease soil.
