Hello,
I would like to use SU2 for hypersonic flow. I need to calculate heat transfer to some simple shapes. 1. Has SU2 capabilities for hypersonic flow calculation? I saw in one presentation on SU2 website, that multi-species plasma simulation gives good results on heat transfer: http://su2.stanford.edu/presentation...ion_to_SU2.pdf (page 13 (bottom-right)). But for me, it looks that there is no PLASMA_NAVIER_STOKES physical model in version 3 of SU2. 2. Is there a plasma equations in version 3 of SU2? Instead I saw that there is two new physical problems: TNE2_EULER and TNE2_NAVIER_STOKES. 3. Is this the physical problem which should be used for hypersonic simulations? Could it be used with multi-species model? 4. Which multicomponent diffusion model is used? Is it accounts for ambipolar diffusion? I hope you could help me at least with some of this questions. Thank you! |

Hello Gengen,
Thanks for your interest in SU2. Yes, SU2 is capable of hypersonic flow simulations. For Mach ranges where no significant chemical reactions occur, the standard solver can be used with a number of low-disspation upwind spatial discretization methods. For high-hypersonic free stream conditions, SU2 has a module that can simulate gas mixtures in thermochemical nonequilibrium. This "TNE2" module is a single-fluid, two-temperature methodology that assumes equilibrium between translational-rotational and vibrational-electronic energy storage modes. Chemical reactions are handled using a finite-rate Arrhenius model with rate coefficients determined in accordance with Park's 1990 model. The viscous capability of the TNE2 solver is still in development, but we hope to finish the implementation and validate the solver in the next few weeks, so please stay tuned for updates. The transport coefficients (diffusion coefficients, viscosity, and thermal conductivities) are determined using the Gupta-Yos model. Please let me know if you have more questions, thanks. -Sean |

Did you finished the viscosity implementation?

Will you commit it to the master branch on github repo?

Just wondering if there have been any recent updates--I see v.4 was just released--to SU2's hypersonic capabilities (alternative gas models, etc.)

Hi,
If anybody can help me to solve hypersonic nozzle flow for real gas. The to make gama as a function of temperature? I am using SU2 4.1.0 version. Regards |

Hey I'm interested in modelling hypersonic flow with chemical reactions in SU2, I would like to know about the state of the module TNE2.
I have the SU2 version 4.3.0 and I cannot find it. Thanks!! |

Hi,
SU2 is updated to v5.0. Is there any new addition to flows in hypersonic flow? What about the real gas with viscous effects in the TNE2 solver? |
