WebLighthill applied his method to problems involving partial differential equations when the zeroth order solution is obtained from a reduced linear equation of equal order as the exact equation. It soon becomes apparent, however, t.hat Lighthill's original purpose of uniform validity throughout the domain of interest cannot always be realized. WebSolution of Lighthill’s acoustic analogy Lighthill’s equation in pressure form is used to study the sound generation, 1 c2 ∞ ∂2p ∂t2 −∇2 p = ∂ ∂xi∂xj (ρuiuj −τij)− ∂2ρe ∂t2, (2) where variables in the far field are denoted by a subscript ∞. In the above, p is the pressure, u is the velocity, τis the viscous
