Does anyone know of the paper(s) which first investigated the use of the D3Q7(or D3Q6) BGK-LBMs for the advection-diffusion equation? I found many articles mentioning them briefly, but I cannot track it down for referencing…
It depends what you want - I don’t have the initial reference, but I have the specifications for D3Q7 (equilibrium functions and so on). Please let me know if you need the paper with the equilibrium functions specified.

but I have to warn you, I. Ginzburgs papers a hard to read. This would also be a good starting point:
