RISNovel Wentzel–Kramers–Brillouin Solutions to the Nonisentropic Helmholtz Equation in a Nonuniform Duct With Mean Temperature Gradient and Mean Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We derive the generalized Helmholtz equation (GHE) governing nonisentropic acoustic fluctuations in a quasi 1D duct with nonuniform cross section, mean temperature gradient, and nonuniform mean flow. Nonisentropic effects ...
Biot Theory-Based Finite Element Modeling of Continuous Ultrasound Propagation Through Microscale Articular Cartilage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Low-intensity ultrasound has shown promise in promoting the healing and regeneration of articular cartilage degraded by osteoarthritis. In this study, a two-dimensional finite element method (FEM) model was developed for ...
