A three-time-scale singular perturbation control law is designed for a nonlinear helicopter model in vertical flight.
During the simulations the seabed has been modelled using a hysteretic non-linear model in vertical seabed direction, and bilinear and trilinear models in the lateral seabed direction.
To address this, we considered the effect of churn flow and developed the original liquid film flow model in vertical upward flow by suggesting that calculation starts from the onset of churn flow rather than annular flow.
To implement the workflow, Ansari et al. (1994) mechanistic two-phase flow hydrodynamic model in vertical wells is coupled with two Asphaltene precipitation thermodynamic models, namely de Boer et al. (1995), and Wang et al. (2006).
The objective of this study is to develop a heat-transfer model for gas liquid flow that is consistent with the hydrodynamic model in vertical wellbore annuli.
The regular patterns of vibration have been studied using the simplified model in vertical direction in previous sections, then in this section, a 3D rigid-flexible coupled railway vehicle system dynamics model is built based on the MBS theory and the finite element method (FEM) to discuss the vibration of carbody and equipment in the real wheel-rail contact and track excitation condition.
