6. Adaptive Algorithms and High Order Stabilization for Finite Element Computation of Turbulent Compressible Flow
Abstract : This work develops finite element methods with high order stabilization, and robust and efficient adaptive algorithms for Large Eddy Simulation of turbulent compressible flows. The equations are approximated by continuous piecewise linear functions in space, and the time discretization is done in implicit/explicit fashion: the second order Crank-Nicholson method and third/fourth order explicit Runge-Kutta methods.

7. Resistance of Circular and Polygonal Steel Towers for Wind Turbines : Down scale component experiments and Finite element analysis
Abstract : With increasing demand of sustainable energy production, the harvesting of wind power by using wind turbines have become increasingly important over the last few decades. Most of the wind turbine towers are made from steel. Towers are an important part of the investment in wind parks and contribute about 20% of costs for the onshore towers. READ MORE
