Studies on Fluid-Thermal-Structural Coupling for Aerothermoelasticity in Hypersonic Flow

A Quasi-Steady Method for Unsteady Flows over Surfaces with Structural Deformation

“…이 때문에 공 력, 구조 변형에 대한 축약모델(reduced-order model)을 구축하고, 이들을 통합하여 공탄성 혹 은 열공탄성(aerothermoelastics) 해석을 수행하는 방법론을 연구하고 있다 [1][2][3][4][5][6][7][8][9].…”

“…한편, 미국의 McNamara 교수와 Cesnik 교수 연구팀은 Kriging 및 POD 기법을 적용하여 공 력, 구조, 열전달에 대한 축약모델 구축하고 [3][4][5][6][7], 이를 이용해 초음속 플러터해석을 수행한 바 있 다 [7][8][9]. 특히 이들은 초음속 비정상(unsteady) 표 면 압력 분포를 축약 계산하기 위해 피스톤 이론 을 적용하였다.…”

Transient Temperature Effects on the Aerothermoelastic Response of a Simple Wing

“…This showed that the extreme aerodynamic heating, combined with the aerodynamic pressure that acts over the system, produces complex fluid-thermal-structural interactions [30]. Due to this complexity, transient thermal effects have only been investigated using loose coupling [13,14], aside from a closely coupled solution on a simple two-dimensional geometry [31].…”

One Low-cost Quartz Lamp Radiation Aerodynamic Heating Simulation Experiment System with Control Law Flexible Adjustment Feature

“…It must be considered in the design of aircraft structure strength [1][2][3] . There are some kinds of methods for simulating aerodynamic heating, such as convective heating, radiation heating and conduction heating [4][5][6] .…”
