Hi, how do you describe the wave function of fire or a flame?

A flame consists of air and some flammable material of high temperature - so high that some atoms get ionized.

However, it is a large system in contact with its environment. There is no such thing as "the wave function of a flame". Depending on your favourite interpretation of QM, it does not have a wave function at all, you cannot observe the wave function or the wave function has many, (nearly) disconnected components and you cannot really tell what you call "the flame" in terms of the wave function.

Sorry, your question does not make any sense.

A bohmian wave function is physical... but what is its shape with respect to an object?

No, technically, most particles don't have a wavefunction. A wavefunction (in position space), when it exists at all (not always true in relativistic cases), is the spatial projection of a pure state (a ket). A ket can only describe a closed system, or one whose environment is wholly classical and perfectly well known. That's a useful approximation in many cases, but not in general. For a general case, the quantum states are described by density operators.
