In this paper, we will apply cubic B-splines on a uniform mesh to explore the numerical solutions and derivatives of class nonlinear second-order boundary value problems with two dependent variables.Our new method is based spline interpolation.The analytical any-order can be well approximated 4th order accuracy.Furthermore, our also able solve general 4th-order two-point problems.Numerical results show that very practical effective.
A new gust load alleviation technique is presented in this paper based on active flow control. Numerical studies are conducted to investigate the beneficial effects aerodynamic characteristics of quasi "Global Hawk" airfoil using arrays jets during process. Based unsteady Navier-Stokes equations, grid-velocity method introduced simulate influence, and dynamic response vertical perturbation investigated for as well. An surface transpiration boundary condition enforced over a user specified...
The network distance service obtains the latency among large-scale nodes. With increasing numbers of participating nodes, has to balance accuracy and scalability. network-coordinate methods scale well by embedding pairwise into a low-dimensional coordinate system. prediction errors are iteratively optimized adjusting coordinates with respect neighbors. Unfortunately, optimization process is vulnerable inaccurate coordinates, leading destabilized positions. In this paper, we propose RMF,...
Numerical studies were conducted to investigate the beneficial effects of using arrays jets on aerodynamic characteristics High-altitude Long-endurance Unmanned Aerial Vehicle (HALE-UAV) airfoil. Flowfield predictions made by an unsteady, two-dimensional, compressible Navier-Stokes flow solver. An unsteady surface transpiration boundary condition was enforced over a user-specified portion airfoil's upper emulate time-varied velocity out and into surface. Five flow-control techniques for...
Compared with conventional drones, distributed powered drones have significant advantages in handling stability characteristics, lift and drag takeoff landing performance. However, there are also challenges such as aerodynamic interference of multi slipstream, distributed-power/wing strong-coupling dynamic modeling, redundant control allocation distributed-power mechanisms. The paper has carried out the research on modeling method, flight dynamics characteristics analysis, design strategy...
We mainly present the error analysis for two new cubic spline based methods; one is a lacunary interpolation method and other very simple quasi method. The methods are able to reconstruct function its first derivatives from noisy data. explicit bounds given proved. Numerical tests comparisons performed. results verify efficiency of our methods.
