Hypersonic Combustion in Scramjet Methodology

Scramjets are a type of ramjets that can travel at hypersonic speed while there is no motion device in its engine. Scramjet technology started from the development of the ramjet.

The ramjets might not achieve supersonic speed, while scramjets fly at hypersonic speed. Supersonic speed means the Mach number of more than 1, while hypersonic represents more than 5.

In this project, Hypersonic Combustion in a scramjet engine is simulated. The Mach number of inlet air is set to 6, and the temperature of the whole domain equals 300k.

At the middle part of the nozzle, in which the Mach number reaches 1, hydrogen injects into the flow with a Mach number of more than 1, and consequently, the combustion will occur in the nozzle.

The species transport model and the volumetric sub-model are enabled to model the combustion process. The air is considered an ideal gas to change the density during combustion.

First-order accuracy is chosen for parameters to reach a suitable convergence, and relaxation factors are set at a lower value than the default amount in Ansys Fluent software. Moreover, the standard k-epsilon model is used to solve turbulent fluid equations.

Hypersonic Combustion in Scramjet Conclusion

At the end of the solution process, two-dimensional contours and vectors of flow pressure, temperature, velocity, Mach number, density, and turbulence intensity are obtained.

At first, airflow enters the domain through the inlet face and moves to the combustion portion while the speed decreases to Mach number 1. Then advances to the outlet at a higher speed.

Due to combustion, the amount of temperature passes 4000 K. Also, the effect of viscous heating is visible in elements near the wall.

    I was wondering how the species transport model and volumetric sub-model work in the simulation of hypersonic combustion?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In the simulation, the species transport model is employed to account for the mixing of reactants and products in the flow, whereas the volumetric sub-model is utilized for simulating the actual combustion reaction happening throughout the flow. These models work in tandem to replicate the chemical reactions and heat release, essential for accurately simulating hypersonic combustion within a scramjet.

    I’m curious to know how the introduction of hydrogen in the combustion chamber impacts the overall performance of the scramjet—does it significantly improve thrust, and how is that demonstrated in the simulation results?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The introduction of hydrogen as a fuel in the combustion chamber significantly impacts the scramjet’s performance by dramatically increasing the combustion temperature, which then contributes to higher exhaust velocities and thrust. The CFD simulation results demonstrate this through the high-temperature contours that exceed 4000 K, especially downstream of the combustion chamber where the hydrogen is injected and combusts with the incoming air, resulting in hypersonic expansion and increased thrust.

    I’m curious, how is hydrogen fuel introduced into the supersonic air stream, and how is it ignited?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In this simulation, hydrogen fuel is introduced into the supersonic air stream at the section where the Mach number is around 1, which is often referred to as the throat or isolator of the combuster. The hydrogen is injected at speeds above Mach 1 to ensure effective mixing with the supersonically-moving air. Ignition occurs due to the high temperature and pressure inside the combustion chamber, which are beyond the ignition point of the hydrogen-air mixture. This phenomenon is captured realistically by activating the species transport model and reacting flow simulation within ANSYS Fluent, which computes the combustion process in conjunction with the fluid flow equations.

    I’m fascinated by the hypersonic combustion process/fuel-air reaction you’ve detailed. Could you explain how viscous heating affects combustion efficiency in these extreme conditions?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Viscous heating has a significant effect on the efficiency of combustion in scramjets operating at hypersonic speeds. As airflow over the surfaces generates friction, this friction heats up the gases, which enhances the combustion process by providing additional energy required for fuel molecules to react with the oxidizer. As such, controlling and optimizing viscous heating is crucial for maximizing combustion efficiency in these extreme flight conditions.

    Can you explain how hydrogen is injected into the flow within the scramjet model and what impact it has on the overall combustion process?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In the simulation, hydrogen is injected into the flow at the point where the Mach number reaches 1 within the nozzle. This means that the hydrogen is introduced at supersonic speeds. During its injection, it combusts with the incoming air due to high temperatures and speeds, significantly contributing to the scramjet’s thrust. The combustion increases the flow’s temperature and, therefore, its volume, resulting in increased exhaust speed—this acts to provide additional thrust for the scramjet.

    I found the velocity changes across different sections of the scramjet intriguing. Can you explain how the simulation showcases this change in velocity, especially at the combustion portion of the scramjet?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Absolutely, the simulation provides detailed insights into the velocity changes. It’s designed to showcase the gradual deceleration of the airflow to a Mach number of 1 at the midpoint of the engine’s nozzle. At this location, hydrogen is injected, initiating combustion and expanding the gases. This process increases the gas velocity again, propelling it towards the outlet at a much higher speed. The contours and vectors generated in the simulation effectively illustrate this dynamic change throughout the scramjet.
