Control surface deployment in a supersonic flow has many applications, including control, mixing, and body-force regulation. The extent of control deflections introduces varying unsteadiness. resulting fluid dynamics influence the downstream characteristics fluid–structure interactions significantly. In order to understand gas dynamics, an axisymmetric cylindrical body with sharp-tip cone at ze...

Fundamental frequencies of solid and annular elliptical plates were approximated using the static deflections by means finite element method (FEM) without computing eigenvalues. The problem was formulated within framework first order shear deformation theory (FSDT). effects (i) inner outer boundary conditions, (ii) size perforation, (iii) aspect ratio, (iv) thickness plate on performance examin...
