Abstract
Petrov type III, shear‐free, perfect fluid solutions of the Einstein field equations, with a barotropic equation of statep=p(w) satisfying w+p≢0, are investigated. It is shown that if the acceleration of the fluid is orthogonal to the two‐spaces spanned by the repeated principal null direction of the Weyl tensor and the fluid four‐velocity, or if the fluid four‐velocity lies in the two‐spaces spanned by the principal null directions of the Weyl tensor, then the fluid’s volume expansion is zero.
