WebLord Rayleigh, in full John William Strutt, 3rd Baron Rayleigh of Terling Place, (born November 12, 1842, Langford Grove, Maldon, Essex, England—died June 30, 1919, Terling Place, Witham, Essex), English physical scientist who made fundamental discoveries in the fields of acoustics and optics that are basic to the theory of wave propagation in fluids. … WebRayleigh Damping. A common method of modeling damping is Rayleigh damping, where two damping coefficients are specified. This type of damping is not directly related to any physical process, but must be seen as a way to take the total damping of a structure into account. Rayleigh damping introduces damping in a form based on Equation 2-20. WebUse rayleigh_flow with mtype values 'templo' and 'temphi'..
