Description

Description:

In this project, the rocket engine is simulated using ANSYS Fluent. A rocket engine is a propulsion system that provides the force necessary to launch a rocket into space. It is a complex mechanism that combines fuel and oxidizer to produce high-temperature, high-pressure gases expelled from a nozzle to generate thrust. Rocket engines can be classified into two main types: liquid and solid-fueled. Liquid-fueled engines are more complex and use liquid fuel and oxidizers pumped into a combustion chamber where they are ignited and burned. On the other hand, solid-fueled engines use a solid fuel that has been pre-mixed with an oxidizer and is burned at a controlled rate.

Rocket engines are crucial components of any rocket launch, and their performance is essential to the mission’s success. Engineers spend years designing, testing, and improving rocket engines to increase their efficiency, reliability, and safety. In addition, developing advanced materials, such as carbon fiber composites and high-temperature alloys, has created more powerful and durable rocket engines. Using rocket engines has enabled humanity to explore space and expand our universe’s knowledge. From sending satellites into orbit to exploring other planets, rocket engines have played a pivotal role in some of the most groundbreaking achievements in human history. As technology advances, the potential of rocket engines to revolutionize space exploration and travel becomes ever more significant.

Rocket engine

CFD simulations are used to model and analyze the flow of fluids and gases within a rocket engine, providing engineers with a detailed understanding of the complex physics involved in the combustion process. By accurately predicting the behavior of the combustion gases, CFD simulations can optimize the engine’s design, improving its performance, efficiency, and safety. One of the main applications of CFD simulations in rocket engine design is the prediction of combustion stability. Combustion instability can lead to oscillations and vibrations within the engine, which can cause structural damage, reduce engine performance, and even lead to catastrophic failure. By simulating the combustion process and analyzing the behavior of the combustion gases, engineers can identify potential instability issues and make design modifications to prevent them.

Another important application of CFD simulations in rocket engine design is predicting thermal loads. The high temperatures generated during the combustion process can cause significant thermal stresses on the engine components, leading to failure. By simulating the flow of heat within the engine and predicting the distribution of temperatures, engineers can design more robust engine components that can withstand the thermal stresses of operation.

Method:

The geometry of this project has been drawn using Space Claim software. The meshing of this geometry has been done using Ansys Meshing software, and the number of elements used for this project is 1051882. The input boundary condition is set to a pressure far field with a pressure of 10 atmospheres and a Mach number of 0.1. The outlet boundary condition is set to pressure outlet with a gauge pressure of zero Pascal.

Result:

After simulation, we can observe the velocity, pressure, and temperature contours.
