Hi,

I'm considering to hire a freelance with access to Ansys or OpenFoam for exchanging solid model designs of a simple can-annular combustion chamber design and analysis from my existing 3d models to suit.
(Edit) I should have indicated our timing and application seek an individual having time and availability to approach this need working remotely on a secured server stack. The current developments involve EGR initiated high speed equivalence combustion models less than three milliseconds which pushes the boundaries for specific geometries as well as down stream volume and modelling considerations seeking improvements in NoX and Co2 emissions with secondary carbon reformation modeling. This means familiarity with 3D modeling of initial geometries and reaction flows as well as basic fluid domain modeling. Expected efforts could rise to a 45 day window upwards of 16 hours per day initial development effort before leveling off to a more forgiving improvement approach long term.
Process approaches pre-mixed or non-premixed fuel input of gaseous methane or propane including EGR fractions and integrated recuperative pre-heat as well as secondary carbon reformation inputs.

Factors of interest are...

Scaling references evaluating turbocharger prime mover model to determine smallest possible turbocharger with size matched combustion chamber solid design model to identify sustainable operation.

The need is to evaluate combustion and emissions fraction properties versus various staged flame tube airflow application to seek smallest practical turbo with reliably low emissions.

The CFD candidate would need to know combustion thermo-dynamics and be able to exchange dialog on various gas phase properties, turbulence, velocities, toroid turbulence modelling and flame retention / volume / velocity profiling and other typical features in Brayton cycle design.

There is an interest in matching a smaller simulation environment here to coordinate replay and review, either Ansys or OpenFoam.

There may be a longer term potential for on-going work if success is found among real world results given bench testing proofs of concept.

Project hours are based around Eastern Standard Time, but can also be flexible to other's time zones and working schedules.

Thanks in advance,

Mike

Hi, Dear Urbansound! Hope you enjoy good health and doing well.

I come across your posted Combustion Modelling project. I have relevant experience of CFD combustion modelling.

In my MSc thesis I developed code for gaseous fuel combustion, designed combustor, and performed CFD/ reacting flow simulations for gas turbine engine in ANSYS/ CFX. I designed and performed modelling for entire Power Cycle.

During my PhD, I developed comprehensive code for chemical reactions, multi-phase & reacting flow, developed Equation of States (EOS). I performed comprehensive simulations by implementing the code in the form of PDEs in COMSOL Multiphysics. I published three papers in international journal of repute.

Recently, I have developed a model/ code for combustion of low-btu/ heating value fuels to be produced from gas wells where I suggested and analysed staged/flame-less combustion for a stable flame.

Though your intended project is complex in nature, I will be happy to discuss and help.

Regards,

Dr. Nawaz Ahmad, PhD

Thank you @fluidmodeller, for your reply and consideration, good health to you as well.

Please watch for contact on private message from urbansound for further details.
The thread here is mainly a contact point in our current outreach.
