...Y.S. Kim; H.I. Park Purpose The purpose of this paper is to examine the feasibility of committee neural network (CNN) theory for the improvement of accuracy and consistency of the neural network model on the estimation of preconsolidation pressure from the field piezocone measurements. Design...

...Xiao Yexiang; Wang Zhengwei; Yan Zongguo; Li Mingan; Xiao Ming; Liu Dingyou Purpose The purpose of this paper is to describe how the hydraulic performance and pressure fluctuations in the entire flow passage of a Francis turbine were predicted numerically for the highest head. The calculations...

...Shuhong Liu; Jianqiang Mai; Jie Shao; Yulin Wu Purpose The purpose of this paper is to predict pressure pulsation in Kaplan hydraulic turbines. Design/methodology/approach State of the art numerical simulation techniques are employed to simulate three‐dimensional flows in the whole flow...

...Fuad M. Khoshnaw; Namam M. Ahmed Purpose The purpose of this paper is to investigate the effect of pressure angle, and module of spur gear teeth on stress concentration factor, using photoelasticity method, and numerical MSC/NASTRAN finite element package. Design/methodology/approach...

...Andrea P. Assanelli; Rita G. Toscano; Daniel H. Johnson; Eduardo N. Dvorkin The production of steel pipes with guaranteed external collapse pressure (e.g. high collapse casings for oil wells) requires the implementation of an accurate process control. To develop that process control it is necessary...
