1Calculation of terminal velocity in transitional flow for spherical particle显示文摘The terminal velocity has been widely used in extensive fields,but the complexity of drag coefficient expression leads to the calculation of terminal velocity in transitional flow e1 < Re 6 1000 T with much more difficulty than those in laminar flow eRe 6 1T and turbulent flow eRe P 1000 T.This paper summarized and compared 24 drag coefficient correlations,and developed an expression for calculating the terminal velocity in transitional flow,and also analyzed the effects of particle density and size,fluid density and viscosity on terminal velocity.The results show that 19 of 24 previously published correlations for drag coefficient have good prediction performance and can be used for calculating the terminal velocity in the entire transitional flow with higher accuracy.Adapting two dimensionless parameters(w*,d*),a proposed explicit correlation,w*=-25:68654 exp(-d*/77:02069)+24:89826,is attained in transitional flow with good performance,which is helpful in calculating the terminal velocity.Zhang Lei Honaker Ricky Liu Wenli Men Dongpo Chen Jinxiang 2015International Journal of Mining Science and Technology2015,25,2:0
