A Study on the Inner Surface Pressure Distribution of Fluid in Ninety Degree Elbow Pipe

Abstract:

On the premise of the simulation data for the inner fuild passing the elbow pipe by means of software named FLUENT and dimensional analysis, the formula modle of inner surface pressure for elbow pipes came up by analyzing the relationships among the inner surface pressure P ,the fluid outlet pressure P₀ ,axial angle α, circular angle β and the degree of curvature k; Depending on the inner surface pressure data simulated under 150 kinds of conditions, the pressure formula was fitted by means of 1stOpt software; The verification results show that the calculated value by the formula matched with the value of simulation by FLUENT software very well, the maximum relative error was 0.004%, and the research conclusion layed the theoretical groundwork for the design of the high pressure and high velocity elbow.
