Natuurlike konveksie onderworpe aan klank

M.Ing. (Mechanical Engineering) / An experimental investigation has been carried out to study the influence of sound waves on the transition from laminar to turbulent flow in the boundary layer associated with natural convection from a vertical flat plate with uniform surface heat flux. A relationship exists between frequency and Grashof number at transition. Buckling flow theory provides a means of explaining this relationship. Numerical solutions for the temperature and velocity distributions in an enclosed cavity with one heated vertical wall have been obtained. The frequency of applied sound waves at which transition in the boundary layer would occur, is predicted.
