Automatic steering control of unmanned vehicles
(2000)The problem of robust automatic steering of an autonomous unmanned vehicle is studied. The problem is solved using a robust P-D feedback controller feeding back the path error and the front steering angle. The design goal ... -
Comparing the effect of three transition models on the CFD predictions of a NACA0012 airfoil aerodynamics
(2016)The ability to accurately predict transition is important for flows around airfoils, especially at low Reynolds numbers. Transition from laminar to turbulent flow strongly influences the flow separation and the skin friction, ... -
Controller design for lateral manoeuvres in electromagnetic wind tunnels
(1996)The roll angle, the yaw angle and the side-slip position of test aircrafts in electromagnetic wind tunnels, are independently controlled. The problem is proven to be always solvable by applying a static state feedback law ... -
Numerical investigation of heavy fuel oil droplet breakup enhancement with water emulsions
(2020)The heating and explosive boiling leading to fragmentation of immiscible heavy fuel oil-water droplets, termed as W/HFO emulsions, is predicted numerically by solving the incompressible Navier-Stokes and energy equations ... -
Uncertainty propagation for robust aerodynamic shape optimization
(2014)Three algorithms for uncertainty propagation and robust aerodynamic optimization are presented in this paper. The perturbation method based on first and second-order Taylor expansion, the asymptotic expansion based on ... -
Yearly numerical evaluation of greenhouse cover materials
(2018)The greenhouse internal microclimate, and consequently the plants growth, is formed from the combination of available solar radiation and ventilation. Transpiration and photosynthesis are affected by the PAR levels, as ...
