- Abstract
The flowing condition and the pressure on inner surface of ethylene in the 90°elbow pipe were simulated by means of FLUENT software, on the condition of 4 kinds of fluid density , fluid inlet velocity v, fluid outlet pressure P0, degree curvature k=R/d respectively. The database of elbow pipe pressure on inner surface distribution is established meanwhile. Based on the property of Normal distribution, Trigonometric function, Exponential function and taken account of elbow pipe pressure on inner surface distribution under different parameters influence, the elbow pipe pressure distribution model can be fitted out by 1stOpt software. Through compared the simulated values by FLUENT with computed values by Equation, the agreement is high, that the maximum relative error between them is only 0.024%. The research conclusion contributes to structural design and safety evaluation of the elbow pipe.
