Large eddy simulation (LES) of flow in a wind farm is studied in neutral as well as thermally stratified atmospheric boundary layer (ABL). An approach has been practiced to simulate the flow in a fully developed wind farm boundary layer. The approach is based on the Immersed Boundary Method...

- Oscillations of stratified fluids. Kopachevskii, N.; Tsvetkov, D. // Journal of Mathematical Sciences;Jan2010, Vol. 164 Issue 4, p574
We study the problem on small motions and normal oscillations of a system of two heavy immiscible stratified fluids partially filling a fixed vessel. The lower fluid is assumed to be viscous, while the upper one is assumed to be ideal. We find sufficient existence conditions for a strong (with...

- POSITIVE SOLUTIONS FOR A FOURTH ORDER BOUNDARY VALUE PROBLEM. Bo Yang // Electronic Journal of Qualitative Theory of Differential Equatio;Mar2005, p1
We consider a boundary value problem for the beam equation, in which the boundary conditions mean that the beam is embedded at one end and free at the other end. Some new estimates to the positive solutions to the boundary value problem are obtained. Some sufficient conditions for the existence...

- On an optimal control problem in the Voigt model of the motion of a viscoelastic fluid. Zvyagin, V.; Kuzmin, M. // Journal of Mathematical Sciences;Mar2008, Vol. 149 Issue 5, p1618
The external feedback control problem in the Voigt model of the motion of a viscoelastic fluid is investigated. To this end, we prove the existence of weak solutions of the initial-boundary problem with the multi-valued right-hand side in the model considered and show the existence of a solution...

AbstractÂ Â In this paper we establish the multiplicity of positive solutions to second-order superlinear repulsive singular Neumann boundary value problems. It is proved that such a problem has at least two positive solutions under reasonable conditions. Our nonlinearity may be repulsive...

- A Semigroup Approach to Dynamic Boundary Value Problems. Nickel, Gregor // Semigroup Forum;Sep/Oct2004, Vol. 69 Issue 2, p159
Dynamic boundary value problems occur in many situations and have been studied intensively with various techniques and goals. In this paper we present an abstract treatment of such problems and characterise wellposedness using semigroup methods and results on operator matrices.
