WebJun 21, 2024 · The roughness functions for the rotating disk surfaces were calculated using the similarity law analysis developed by Granville (1978, 1982). The roughness function is the magnitude of the downward shift in the logarithmic region of the mean velocity profile of the boundary layer that is caused by surface roughness (Schultz and Myers 2003). WebUsing autocorrelation analysis, we derive an approximate length scale for the surface roughness on the order of 5.7 μ m (Quantifying Biofilm Roughness from Confocal Biofilm Images). We speculate that clustering on this length scale may be a result of cell division and intercellular Ag43 homodimerization leading to a different effective ...
