Abstract: The paper studies the existence of exponential attractor for the Boussinesq equation with strong damping and clamped boundary condition utt − Δu + Δ2u − Δut − Δg(u) = f(x). The main result is concerned with nonlinearities g(u) with supercritical growth. In that case, we construct a bounded absorbing set with further regularity and obtain quasi‐stability estimates. Then the exponential attractor is established in natural energy space V2 × H.
