The present problem is concerned with the study of deformation of a rotating generalized thermoelastic solid with an overlying infinite thermoelastic fluid due to different forces acting along the interface under the influence of gravity. The components of displacement, force stress, and temperature distribution are first obtained in Laplace and Fourier domains by applying integral transforms, and then obtained in the physical domain by applying a numerical inversion method. Some particular cases are also discussed in the context of the problem. The results are also presented graphically to show the effect of rotation and gravity in the medium.
