Abstract

We establish long-time and large-data existence of a weak solutionto the problem describing three-dimensional unsteady flows of anincompressible fluid, where the viscosity and heat-conductivitycoefficients vary with the temperature. The approach reposes onconsidering the equation for the total energy rather than theequation for the temperature. We consider the spatially periodicproblem.
