A Reduced-Order Model of Heat Transfer Effects on the Dynamics of Bubbles [PDF]
, 2002 The Rayleigh-Plesset equation has been used extensively to model spherical bubble dynamics, yet it has been shown that it cannot correctly capture damping effects due to mass and thermal diffusion.

Influence of the upper gravity-wave damping layer on precipitation over complex terrain
Frontiers in Environmental Science, 2022 The upper boundary condition of a numerical model can significantly influence the model prediction results. This study used the Weather Research and Forecasting model to introduce the Rayleigh damping layer in the complex terrain of southern Gansu, China.

Phonon lineshapes in atom-surface scattering [PDF]
, 2010 Phonon lineshapes in atom-surface scattering are obtained from a simple stochastic model based on the so-called Caldeira-Leggett Hamiltonian. In this single-bath model, the excited phonon resulting from a creation or annihilation event is coupled to a ...

Computation of Rayleigh Damping Coefficients for the Seismic Analysis of a Hydro-Powerhouse
Shock and Vibration, 2017 The mass and stiffness of the upper and lower structures of a powerhouse are different. As such, the first two vibration modes mostly indicate the dynamic characteristics of the upper structure, and the precise seismic response of a powerhouse is ...

Effect of the viscous damping on the seismic response of Low-rise RC frame building
Revista Facultad de Ingeniería Universidad de Antioquia, 2020 The equivalent viscous damping is a key parameter in the prediction of the maximum nonlinear response. Damping constitutes a major source of uncertainty in dynamic analysis. This paper studies the effect of using viscous damping, on the reduction of the

Numerical Simulation of the Infinite Medium of Dry Soil in Dynamic Soil-Structure Interaction Problems [PDF]
Engineering and Technology Journal, 2013 One of the major issues in the dynamic analysis of soil-structure interaction problems is to model the far field medium. The dynamic analysis of soil-structure interaction problems can be carried out by using a numerical solution procedure such as finite

Fast frequency response computation for Rayleigh damping [PDF]
International Journal for Numerical Methods in Engineering, 2007 AbstractWe present a model reduction Lanczos method for the computation of frequency response functions of Rayleigh damping problems. The connection with modal extraction and modal superposition is made. The usual model reduction methods require complex arithmetic. With the proposed method, complex arithmetic is only used for the reduced problem.
