Under the condition of supercooled large droplets (SLD), droplets breakup, splashing and bouncing should be considered. A droplet re-impingement model is applied to better study SLD impingement, and the Mcdonnell Douglas Aerospace (MDA) 3-element airfoils are simulated. Compared with normal model, impingement limits are minished slightly, local water collection efficiency decreases in some degree,...
In this article, we propose a new behavioral thermal modeling method for fast building performance analysis, which is critical for energy-efficient smart building control and management. The new approach is based on two recurrent neutral network architecture to obtain the compact nonlinear thermal models for complicated building. We start with a more realistic building simulation program, EnergyPlus,...
Terrain Aided Navigation (TAN) system has been widely used in aerial and underwater vehicles for its autonomy, anti-electromagnetic interference (anti-EMI) and all-weather advantages. TAN system is also a multi-sensor system usually consists of radar altimeter, barometric altimeter, laser scanner, echo sounder, inertial navigation system (INS) and so on. It fuses the information from different sensors...
Soil moisture is the central focus of land surface and atmospheric modeling because it controls surface water and energy fluxes and consequently affects land–atmosphere interactions. Although global or regional satellite-derived surface soil moisture data sets are readily available, knowledge about assimilating them into numerical weather prediction (NWP) models is limited. The methods of assimilating...
In order to reuse mechanism model of thermodynamic equipment in power plant simulator and decrease the dependence on personpsilas experience during the modeling and parameter optimization, a novel integrated and intelligent model structure was put forward based on the feedback theory in automatic control principle. The mathematics modeling process was compared with closed loop control system, their...
Vortex levitation can achieve non-contact handling by blowing air into a vortex cup through a tangential nozzle to generate a swirling air flow. In this paper, its dynamic characteristics are analyzed through dynamic pressure response, and a dynamic modeling is developed and verified experimentally. First, we observe the pressure dynamic response inside the cup by making the cup and the work piece...
