![]() ![]() Not relying on a gradient expansion, our findings may be useful in the study of early-time dynamics and in the evolution of shock waves in heavy-ion collisions. Our numerical results indicate that the relaxation towards ideal hydrodynamics is significantly faster in the DTT than in the second-order theory. Manuel was born on January 16 1896, in Corozal,Sucre,Colombia. Finally, we compare, analytically and numerically, the equations of motion of the DTT and its truncation to second-order terms for the case of boost invariant flow. Sol Peralta, 1930 - 1976 Sol Peralta 1930 1976 Sol Peralta was born in month 1930, at birth place, to Manuel Jesus Carrascal Ramos and Rafaela Carrascal Ramos (born Salgado Perez). The DTT satisfies the second law, and is causal in a set of fluid states near equilibrium. We show that the stress-energy tensor constructed from second-order conformal invariants is obtained from the DTT by a consistent adiabatic expansion. ![]() ![]() DTTs go beyond second-order (in velocity gradients) theories, and are closed in the sense that they do not rely on adiabatic expansions. Within the theoretical framework of divergence-type theories (DTTs), we set up a consistent nonlinear hydrodynamical description of a conformal fluid in flat space-time.
