Sph tait equation of state

Web1. jún 2009 · It is the so-called Tait equation, which computes a relative pressure field assuming the atmospheric reference pressure being equal to zero: (6) p = k 0 ρ ρ 0 γ - 1. Here, ρ 0 is the reference fluid density at atmospheric pressure and for the exponent γ typically one uses γ = 7. Eq. (6) approximates the liquid as a weakly compressible fluid. This equation, in pressure form, can be written as where are mass densities at , respectively. For pure water, typical parameters are = 101,325 Pa, = 1000 kg/cu.m, = 2.15 GPa, and = 7.15. [citation needed] Note that this form of the Tate equation of state is identical to that of the Murnaghan equation of state . … Zobraziť viac In fluid mechanics, the Tait equation is an equation of state, used to relate liquid density to hydrostatic pressure. The equation was originally published by Peter Guthrie Tait in 1888 in the form Zobraziť viac In 1895, the original isothermal Tait equation was replaced by Tammann with an equation of the form where Zobraziť viac Following in particular the study of underwater explosions and more precisely the shock waves emitted, J.G. Kirkwood proposed in 1965 a more appropriate form of equation of state to describe high pressures (>1 kbar) by expressing the isentropic … Zobraziť viac A related equation of state that can be used to model liquids is the Tumlirz equation (sometimes called the Tammann equation and originally proposed by Tumlirz in 1909 … Zobraziť viac • Equation of state Zobraziť viac
