Ansys Explosion Simulation: Methane Gas Parameters

Click For Summary
SUMMARY

The forum discussion centers on the need for specific explosion parameters for methane gas (8.5% in air) to conduct simulations in Ansys. The user seeks guidance on five critical parameters: adiabatic exponent (γ), pressure shift, specific internal energy, velocity of explosion, and time of explosion, all at a temperature of 293 K. The lack of predefined methane material in Ansys necessitates user input for accurate simulation results. Participants are encouraged to share their knowledge on these parameters to assist in the simulation process.

PREREQUISITES
  • Understanding of Ansys simulation software
  • Basic knowledge of gas dynamics and thermodynamics
  • Familiarity with explosive material properties
  • Knowledge of chemical reaction parameters
NEXT STEPS
  • Research methane gas properties for explosion simulations
  • Learn how to define custom materials in Ansys
  • Explore the effects of temperature on gas explosion parameters
  • Study the principles of adiabatic processes in gases
USEFUL FOR

This discussion is beneficial for chemical engineers, simulation specialists, and researchers involved in explosion dynamics and safety assessments using Ansys software.

Hi everyone,

I have a problem. I need doing simulation in AnSys about explosion methane (as gas), unfortunately program has not such material and I do not know explosion parameters of methane (8.5% in air). I am enclosing picture with parameter of TNT (AnSys has material TNT), and does someone know about what parameters should has methane gas and could you share with me?

Best regards

My mistake I do not good know program yet, therefore such stupid things came out.I do not good know program yet, therefore such stupid thing gone. Anyway now I would like give correct question.
I saw other option in program. Do you know such parameters of methane gas:
1. Adiabatic exponent γ (without unit),
2. Pressure schift (kPa),
3. Specific internal energy (J/kg)
4. Velocity explosive (mm/s)
5. Time of explosion (s)
For 8,5% methane in air and temperature - 293 K
I am trying looking for, but for me this is not readable.

Regards
