  • Having no or negligible viscosity.

    • ‘If viscosity is artificially added in an inviscid model, it has only a small effect on performance.’
    • ‘The actual model we use is that of a thin elastic plate that overlies an inviscid fluid.’
    • ‘For the high Reynolds numbers commonly associated with insects, birds, and fish, these propulsive forces are generally well described by inviscid flow theory.’
    • ‘Spence studied a two-dimensional airfoil placed in an inviscid, incompressible, steady fluid flow, in particular a thin jet coming from its trailing edge of the airfoil.’
    • ‘In addition, the postulated role of vorticity production near the head is at variance with inviscid, irrotational models.’
