Computational Analysis of Shockwave in Convergent Divergent Nozzle

The objective of this paper is to computationally analyse shock waves in the Convergent Divergent (CD) Nozzle. The commercial CFD code Fluent is employed to analyse the compressible flow through the nozzle. The analysis includes static pressure, temperature, Mach number and density of the flow for different nozzle pressure ratios (NPR i.e., the ratio between exit pressure of the nozzle to ambie...

Flow Analysis and Optimization of Supersonic Rocket Engine Nozzle at Various Divergent Angle using Computational Fluid Dynamics (CFD)

CFD is a branch of Fluid Mechanics which rely on numerical methods and algorithms to solve and analyze problem that involves fluid flow. CFD analysis has been conducted to analyze flow pattern of supersonic rocket nozzle at various degree of divergent angle by using two dimensional axis-symmetric model, which solves governing equation by a control volume method. Variation in parameters like vel...

Control of Nozzle Flow in Suddenly Expanded Duct with Micro Jets

This paper presents results of an experimental investigation carried out to control the base pressure in a suddenly expanded axisymmetric passage. Four micro-jets of 1 mm orifice diameter located at 90 0 intervals along a pitch circle diameter of 1.3 times the nozzle exit diameter in the base region were employed as active controls. The tests were conducted for Mach numbers 1.25, 1.3, 1.48, 1.6...
