# Uniform exponential stability of a fluid-plate interaction model due to thermal effects

This work was supported in part by the ERC advanced grant 668998 (OCLOC) under the EU-s H2020 research program and the Ernst-Mach grant of the Austrian Agency for International Cooperation in Education and Research (OeAD-GmbH)

• We consider a coupled fluid-thermoelastic plate interaction model. The fluid velocity is modeled by the linearized 3D Navier-Stokes equation while the plate dynamics is described by a thermoelastic Kirchoff system. By eliminating the pressure term, the system is reformulated as an abstract evolution problem and its well-posedness is proved by semigroup methods. The dissipation in the system is due to the diffusion of the fluid and heat components. Uniform stability of the coupled system is established through multipliers and the energy method. The multipliers used for thermoelastic plate models in the literature are modified in accordance to the applicability of a certain Stokes map.
