abstract
An large-eddy simulation of a turbulent flow using a dynamic two-parameter model has been carried out for a straight open channel with one flood plain at a Reynolds number of 5,300, based on the hydraulic radius and bulk mean velocity. This can be viewed as an extension of Satoh's simulation [J. Hydr., Coastal and Envir. Engrg. JSCE 628/II-48 (1999) 115] in which the standard Smagorinsky model was employed as an SGS stress model. Overall, the computational results agree quite well with laboratory measurements by Tominaga and Nezu [J. Hydr. Engrg. ASCE 117 (1991) 21] in spite of difference in their Reynolds numbers and show that the present method is a promising tool for natural river predictions.
