Data-driven prediction of unsteady flow over a circular cylinder using deep learning [PDF]

open access: yesJournal of Fluid Mechanics, 2018
Unsteady flow fields over a circular cylinder are used for training and then prediction using four different deep learning networks: generative adversarial networks with and without consideration of conservation laws; and convolutional neural networks ...

A superelement-based method for computing unsteady three-dimensional potential flows in hydraulic turbomachines [PDF]

open access: yes, 1999
A numerical method is presented for the computation of unsteady, three-dimensional potential flows in hydraulic pumps and turbines. The superelement method has been extended in order to eliminate slave degrees of freedom not only from the governing ...

An implicit unified gas-kinetic scheme for unsteady flow in all Knudsen regimes [PDF]

open access: yesJournal of Computational Physics, 2018
The unified gas-kinetic scheme (UGKS) is a direct modeling method for multiple scale transport. Based on the ratio of time step to the particle collision time, the local evolution solution on the mesh size and time step scales is used in the construction

Longitudinal flight dynamics modeling and a flight stability analysis of a monocopter

open access: yesAIP Advances, 2022
A monocopter, which is a biology-inspired aircraft based on the samara, has been proved to have passive flight stability. However, due to the asymmetry of its configurations and the constant rotation during flight, its flight dynamics equation is complex.
