Recent advances in theoretical models of respiratory mechanics Hot!
Bo Huo, Rui-Rong Fu
Abstract

As an important branch of biomedical engineering, respiratory mechanics helps to understand the physiology of the respiratory system and provides fundamental data for developing such clinical technologies as ventilators. To solve different clinical problems, researchers have developed numerous models at various scales that describe biological and mechanical properties of the respiratory system. During the past decade, benefiting from the continuous accumulation of clinical data and the dramat...

Characteristics of compressible flow of supercritical kerosene
Feng-Quan Zhong, Xue-Jun Fan, JingWang, Gong Yu, Jian-Guo Li
Abstract
In this paper, compressible flow of aviation kerosene at supercritical conditions has been studied both numerically and experimentally. The thermophysical properties of supercritical kerosene are calculated using a 10-species surrogate based on the principle of extended corresponding states (ECS). Isentropic acceleration of supercritical kerosene to subsonic and supersonic speeds has been analyzed numerically. It has been found that the isentropic relationships of supercritical kerosene are sign...
Unsteady aerodynamics modeling for flight dynamics application
Qing Wang, Kai-Feng He, Wei-Qi Qian, Tian-Jiao Zhang, Yan-Qing Cheng, Kai-Yuan Wu
Abstract
In view of engineering application, it is practicable to decompose the aerodynamics into three components: the static aerodynamics, the aerodynamic increment due to steady rotations, and the aerodynamic increment due to unsteady separated and vortical flow. The first and the second components can be presented in conventional forms, while the third is described using a one-order differential equation and a radial-basis-function (RBF) network. For an aircraft configuration, the mathematical models...
