Implicit Discontinuous Galerkin Solution on Unstructured Mesh for Turbine Blade Secondary Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To enhance solution accuracy with high-order methods, an implicit solver using the discontinuous Galerkin (DG) discretization on unstructured mesh has been developed. The DG scheme is favored chiefly due to its distinctive ...
Vibration Frequencies and Modes of a Z Shaped Beam With Variable Folding Angles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we investigate the vibration characteristics of a Zshaped beam with variable folding angles which is used to model a folding wing of a morphing aircraft under the condition of a fixed structure. The governing ...
A Second-Order Closure Turbulence Model: New Heat Flux Equations and No Critical Richardson Number
Publisher: American Meteorological Society
Abstract: We formulate a new second-order closure turbulence model by employing a recent closure for the pressure–temperature correlation at the equation level. As a result, we obtain new heat flux equations that avoid the long-standing ...
