Abstract :
The purpose of this study is to simulate the flow pattern at a degree of purity of ninety degrees, which is itself part of the experimental and numerical transformation with the help of three-dimensional organizational fluid dynamics. The numerical modeling used in this study is using Fluent Fluid Dynamic Software. The disturbance model used is K-ε standard and is used in the speed and pressure coupling of the Simpl or Sim pattern, and the Up-Wind solution The second order is used for solving accuracy. The changes in the components of the flow velocity, as well as the secondary flow, have been considered in this research. The results of laboratory data from the reference and numerical modeling paper showed that the flow pattern in the channel bend is widely influenced by the secondary flow and centrifugal force. Takes. Comparison of laboratory data with the numerical model of the software shows that the Flowt software is capable of simulating the flow pattern in a 90-degree bend in a three-dimensional state. By applying the coefficient of energy loss, the accuracy of the channel bending calculations increases.
