dc.description.abstract | In this paper, we study the full compressible Navier--Stokes system in a bounded domain Ω⊂R3
, where the viscosity and heat conductivity depend on temperature in a power law (θb
for some constant b>0
) of Chapman--Enskog. We obtain the local existence of strong solution to the initial-boundary value problem (IBVP), which is not trivial, especially for the nonisentropic system with vacuum and temperature-dependent viscosity. There is degeneracy caused by vacuum, and there is extremely strong nonlinearity caused by variable coefficients, both of which create great difficulty for the a priori estimates, especially for the second-order estimates. First, in order to obtain closed first-order estimates, we introduce a new variable to reformulate the system into a better form and require the measure of initial vacuum domain to be sufficiently small. Second, with the help of a cut-off and straightening out technique, and the thermo-insulated boundary condition, we establish the time involved estimate for the second-order derivative of temperature, which plays a key role in closing the a priori estimates. Moreover, our local existence result holds for the cases that the viscosity and heat conductivity depend on θ
with possibly different power laws (i.e., μ,λ∼θb1
, κ∼θb2
with constants b1,b2∈[0,+∞)
