The following is response is from John,
who is not on this discussion board.

"Due to the complexity of the process, optimizing process
parameters is generally done experimentally through some
design of experiment framework. Modeling of the combustion
process or particle flame interactions can be done using
commercially available CFD software (ANSYS/FLUENT, etc.)
but aspects such as microstructure formation, coating
properties, or the stress state of the coating tend to not
generalize well. While the latter isn't strictly impossible
it tends to be more of a limited academic exercise done
through custom developed codes and I'm not aware of any
useful commercially available software. At the end of
the day nothing really beats the utility of a simple DOE
with some physical intuition as the experiments tend to
be quick and easy with direct feedback. This is especially
true as most models rely on a significant amount of
experimental data for parameter fitting!
Happy to answer any questions on this. I've also linked a
few papers below on process development for HVOF that might
give some insights:"

Subject: Thermal Spray Simulation
Hello all,
I am currently researching Thermal Spray - HVOF coatings. I would like to know if there are any simulation codes or numerical equations which can be used to optimize the thermal spray coating behaviour to achieve a specific property and control the porosity as well. It will be really helpful if someone can guide me regarding the same.
Thanks and stay safe
