WebFrom the same period as the van der Waals equation, Tait’s efforts were part of the first trials to represent the equation-of-state of dense, liquid and solid bodies by continuous functions. The goal was twofold: metrological, to interpolate between experimental results, and to provide experimenters and engineers with the most
WebThe sph/taitwater style computes pressure forces between SPH particles according to Tait’s equation of state: p = B [ ( ρ ρ 0) γ − 1] where γ = 7 and B = c 0 2 ρ 0 / γ, with ρ 0 being the reference density and c 0 the reference speed of sound. Webv∗ are reintroduced in the Euler equations instead of p and v to obtain the new solutions compatible with in-viscid flow discontinuities. In SPH, we pay attention in particular (Inutsuka 2002; Parshikov & Medin 2002) to the particle pressures pi and pj, in the SPH formula-tion of the momentum and energy equations (8) and (9),
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.
