Abstract

We develop the boundary derivative expansion (BDE) formalism of fluid/gravity correspondence to nonconformal version through the compactified, near-extremal black D4-brane. We offer an explicit calculation of 9 second order transport coefficients, i.e., the τπ, τπ, τΠ, λ1,2,3\tau_\pi,~\tau_\pi^*,~\tau_\Pi,~\lambda_{1,2,3} and ξ1,2,3\xi_{1,2,3} for the strongly coupled, uncharged and nonconformal relativistic fluid which is the holographic dual of compactified, near extremal black D4-brane. We also show that the nonconformal fluid considered in this work is free of causal problem and admits the Haack-Yarom relation 4λ1+λ2=2ητπ4\lambda_1+\lambda_2=2\eta\tau_\pi.
