Air Flow Analysis and Effect of Angle on Rotation Vane Blade through 90 Degree by Computational Fluid Dynamic

Abstract

This article presents the result of Computational Fluid Dynamics (CFD) simulations of airflow velocity and pressure distribution at two types of rotation vane at a 90-degree pipe bend: (1) 10⁰ rotation vane blade angle and (2) 33⁰ rotation vane blade angle in 0.1m pipe cross-section. The pressure drops of the two rotation vanes were also calculated for comparison. The CFD-based empirical model can predict the velocity and pressure of the pipelines model, with the modeling results validated by a previous study. The input parameters to ANSYS Fluent are viscosity, density, and inlet fluid velocity of 10m/s to 30m/s, and the output of the computer simulation is velocity and pressure at two different sections. The simulation results were taken in two sections: (1) A-A and (2) B-B, and each section consisted of 10 points across the cross-section of the pipe with a 0.01m distance between two-point.
