Abstract
Normally, the open water channel is used to analyze the fluid dynamics when fluid flow through the model. The design convergent section approach is consider in order to determine inlet water velocity conditions and the variation of the curve profile. The convergent section is designed using third, fifth and seventh order polynomial equation, respectively. The result to shows that the optimization of the condition was affected uniform water velocity profile in test section. The third order polynomial wall generates maximum water flow speed about 0.25 m/s at 0.05 m/s of inlet water velocity. The fifth order polynomial wall of convergent section was generated maximum water flow speed about 0.31 m/s at 0.05 m/s of inlet water velocity. The seventh order polynomial generates maximum water flow speed about 0.61 m/s at 0.02 m/s of inlet water velocity. The increasing of degree order polynomials were increased water flow speed in test section. The fifth order polynomial wall of convergent section is velocity profile uniform, when Compare with third and seventh order polynomial. ฉ 2017 IEEE.
