Flow Behaviour Of Elbow With Various Geometries Of Nozzle

Elbow is one of the most common components in the pipe line system, where pressure difference occurred as a fluid flow. Due to the pressure difference the centrifugal forces are developed. For this reason, the behavior of the fluid flow in a 90^°elbow for different geometries of nozzle have been studied using the FLUENT software. Ten different models were investigated based on the K-ɛ model of the energy equation. The analysis was simulated in terms of the velocity and pressure contours and comparison is done. The analysis has been done for 10 different models with changing the angle of convergence from 0˚ to 90˚and found that the velocity gradients are increasing and pressure gradients are decreasing in an ascending order of the angles of convergence for nozzle geometry. The software values are compared to the regression values and found to yield good agreement with the simulated values.
