Supercooled large droplet (SLD), which can cause abnormal icing, is a well-known issue in aerospace engineering. Although efforts have been exerted to understand impact dynamics and the supercooled feature film/substrate interface, respectively, thermodynamic effect during SLD process has not received sufficient attention. This work conducts experimental studies determine effects of drop size on thermodynamics for impingement. Through phenomenological reproduction, rapid-freezing...
In this article, the distributed optimization problem is studied for a class of fractional-order nonlinear uncertain multi-agent systems (MASs) with unmeasured states. Each agent represented through system unknown nonlinearities, unmeasurable states and local objective function described by quadratic polynomial function. A penalty constructed sum functions integrating consensus conditions MASs. Radial basis Neural-networks (RBFNNs) Neural networks (NN) state observer are applied to...
As the density and integration of electronic equipment continue to increase, it becomes necessary build micro-channel heat sinks with more efficient cooling effects solve removal issue. This paper proposes a series obstructions established on smooth water-cooled analyzes transfer flow performance from viewpoint fluid dynamics. By adjusting unilateral side length obstructions, simulation conducted comparative analysis between seven different obstruction shapes sinks, focusing Nusselt number,...
Given the importance of understanding new FAR25, Appendix O certification, supercooled large droplet icing characteristics and its damages should be specified because serious hazard to in-flight safety aircraft engineering. This study compares feature aerodynamic degradation high-lift devices under different diameter conditions using a verified numerical method SJTUICE (a ice accretion simulating code by Shanghai Jiao Tong Univeristy). With two flow freezing time-steps T f s , accuracies on...
This paper studied the unsteadiness of vortex motion produced by a three-dimensional wing section with horn/ridge ice contamination. Using improved delayed detached eddy simulation method, multi-scale and their associated flow structures were successfully captured. Results have shown diversity scales at different time series, including shear layer instability, pairing, co-rotating breaking up. Proper orthogonal decomposition was then introduced to extract characteristic shedding modes...
In this study, an observer based sliding mode control (SMC) scheme is proposed for vibration suppression of subsonic piezo-composite plate in the presence time varying measurement delay by using piezoelectric patch (PZT) actuator. Firstly, state space form model derived Hamilton’s principle with assumed method. Then involving constructed and sufficient condition asymptotic stability Lyapunov-Krasovskii function, descriptor method linear matrix inequalities (LMIs) estimation error dynamical...
This paper investigates the distributed optimization problem for a class of nonlinear uncertain multi-agent systems with unmeasured states, switched parameters, and directed communication topologies changing in control process. To achieve goal optimizing global objective function, penalty function is constructed through making up sum local functions integrating consensus conditions to utilize neighboring information. Radial basis neural-networks state observer are applied approximate unknown...
