Flow Analysis of Convergent and Divergent Nozzle Using Computational Fluid Dynamics (CFD)

Abstract

The device that controls the direction of fluid
flow is Nozzle. Pipes of varying cross-sectional
areas are used to design Nozzles. Nozzles help
in controlling various characteristics of the
fluid-like rate of flow, speed, direction, mass,
shape, and pressure. The nozzle usually
converts the chemical-thermal energy
generated in the combustion chamber into
kinetic energy. Generally in Nozzles
conversion of high pressure, low velocity,
high-temperature gases into gases of low
pressure, high velocity, and low temperature
takes place. Our study is carried out on
Convergent and Divergent nozzles for
analysis of flow using computational fluid
dynamics (CFD). The numerical study is to be
conducted to understand the airflow in a
Convergent-Divergent Nozzle at different
divergence and convergence angles using
three-dimensional models. The present study
is aimed at examining the supersonic flow in
the C-D nozzle at various divergence and
convergence angles. The flow is simulated
using Ansys fluent. The result shows the
variation in the pressure and velocity.
