Turbulent parameters and corresponding sediment transport in curved cross-section channel

Sharma, Anurag / Patel, Mahesh / Kumar, Bimlesh

Experimental investigations have been done to analyze turbulent flow in curved sand bed mobile channel. Measures of turbulent statistics were analyzed for its impending effect on sediment transport. The friction factor and Taylor microscale have been found to decrease with respect to depth. The lower value of von Karman constant has been found for mobile bed channel. Third-order statistics, which shows the skewness and diffusion behavior, has been also analyzed for mobile bed channel. Analysis of bursting events shows that sweep and ejection are the main events for sediment transport.
