Abstract

The aim of this study is to evaluate the effects of valve angle and fluid velocity on pressure drop in pipe flow using ANSYS Fluent software. Flow analyses were conducted using Taguchi L8 orthogonal array with two control factors. The valve angle in the pipe was chosen as the first control factor, while the fluid velocity was selected as the second control factor. The optimum levels of each control factor and its effect on the results were determined using Signal-to-Noise ratio analysis. The significance level and contribution rates of each control factor on the responses were determined using analysis of variance. As a result of this study, the increase of fluid velocity and valve angle causes an increase in pressure drop. Maximum pressure and velocity changes were observed on the valve. It was determined that the effect of the fluid velocity in the pipe on the pressure drop was lower than the effect of the valve angle.
