CFD simulations of the wind environment around an airport terminal building

The 3D Numerical Analysis on the Predictions of Flight Stability at Take-off and Landing (Crosswind 60°)

“…하지만 활주로 주변의 기상변화로 발생되는 여러 가지 유동현상에 대한 연구는 windshear의 예측에 대한 방법이나 이․착륙 중 인 항공기에서 발생되는 와류와 공항운영에 대한 연구가 주로 연구되었으며 [3] [4], 최근에는 비행 장 주변에서 발생되는 유동이 공항 시설물에 미 치는 환경적 영향에 대한 연구가 진행된 정도이 다 [5]. 국내의 경우 본 논문의 선행과제로 진행되 었던 시설물의 단면형상에 의해 발생되는 유동이 이․착륙항공기의 받음각에 미치는 연구와 이러 한 유동으로 인하여 발생되는 ground turbulence 를 감소시키는 연구가 2차원 수치해석으로 수행 되었으며 [6]- [8], 실제 비행장 주변의 모든 환경을 모델링하고 활주로에 수직하게 불어오는 유동이 비행안정성에 미칠 영향을 예측하는 3차원 유동 해석이 연구되어 있다 [9].…”

Energy Research in Airports: A Review

“…During the winter season, the internal loads could exceed the thermal losses, forcing the HVAC system to operate in the cooling mode and not in heating, while during the summer the internal loads are added to the external ones due to the heat exchange by radiation, conduction and convection [13]. In relation to the wind, Neofytou et al [52] investigated the thermal effect of the wind environment around a large airport terminal, in which CFD simulations have been performed.…”

Coupled maps serving the exchange processes on the environmental interfaces regarded as complex systems

“…In papers that would follow we will continue with elaboration of the 1) model of evolvable environmental interfaces and 2) model of forming the functional time of the exchange Figure 1. Examples of environmental interfaces: (a) Ions exchange in metals [9]; (b) Intercellular exchange of biochemical substances [10]; (c) Exchange of air volumes in urban conditions [11]; (d) Migration of insects [12]; (e) Heat exchange in Earth's interior consisting of central core, a mantle surrounding the core and lithosphere; (f) Energy exchange between solid matter and gas in natural conditions [13] and (g) Information exchange in a specific environment model combined with the environment interface describing their interactions [14].…”

“…Through these interfaces environments exchange energy, matter and information (Figure 1). For example, those processes are: a) ions exchange in metals in unrelaxed configuration of ions and metal cores [9]; b) intercellular exchange of biochemical substances [10]; c) exchange of air volumes in a macroscale of urban conditions [11]; d) periodic migrations between populations [12]; e) heat exchange in Earth's interior consisting of central core, a mantle surrounding the core and lithosphere; f) energy exchange between solid matter and gas in natural conditions [13] and g) information exchange in a specific environment model combined with the environment interface describing their interactions [14]. The interactions between parts of the complex environmental interface systems are nonlinear, while their interactions with the surrounding environments are noisy that is mathematically well elaborated in [8,[15][16][17][18][19], among others.…”
