The initial value problem for a generalized Boussinesq model. (English) Zbl 0930.35136
The paper examines the evolution problem for Boussinesq model which describes the coupled mass and heat flow in a viscous incompressible fluid with temperature-dependent viscosity and heat conductivity. Using spectral Galerkin method, the authors prove global existence of weak solutions and local existence of a unique strong solution.
