Webb(I.6) The ratio of the particle velocity to the sound velocity is known as the acoustic Mach numberM. One can see from equation (I.5) thatμ is of the same order as the acoustic Mach number. Substituting (I.4) into the system (I.1)-(I.3), one can reduce it to the form ρ0 ∂u ∂t +∇p− ηΔu− ζ+η/3 graddivu= =−ρ∂u ∂t −(ρ0+ρ)(u∇)u(I.7) ∂ρ ∂t WebbJournal of Theoretical and Computational Acoustics Journal of Theoretical and Computational Acoustics ISSN (print): 2591-7285 ISSN (online): 2591-7811 Formerly known as Journal of Computational Acoustics (JCA) (1993 Vol. 1 Issue 1 - 2024 Vol. 25 Issue 4).
