Abstract We investigate the aerodynamics of a surging wind turbine with numerical simulations based on free wake panel method. start by demonstrating method’s capability to simulate plunging airfoil, which provides some insights that are later used interpret results rotor. then validate method non-surging and discuss strengths weaknesses our approach. Next, we focus UNAFLOW case: was modelled e...

In this paper, the vibrational and buckling analysis of a cylindrical sandwich panel with an elastic core under thermo-mechanical loadings is investigated. The modeled cylindrical sandwich panel as well as its equations of motions and boundary conditions is derived by Hamilton’s principle and the first-order shear deformation theory (FSDT). For the first time in the present study, various bound...

We consider the problem of forecasting multiple time series across multiple cross-sections based solely on the past observations of the series. We propose to use panel vector autoregressive model to capture the inter-dependencies on the past values of the multiple series. We restrict the panel vector autoregressive model to exclude the cross-sectional relationships and propose a method to learn...

Most panel method implementations use both low order basis function representations of the solution and flat panel representations of the body surface. Although several implementations of higher order panel methods exist, difficulties in robustly computing the self term integrals remain. In this paper, methods for integrating the single and double layer self term integrals are presented. The ap...

This paper discusses the use of the 3-dimensional panel method for dynamical system simulation. Specifically, the advantages and disadvantages of model exchange versus co-simulation of the aerodynamics and the dynamical system model are discussed. Based on a trade-off analysis, a set of recommendations for a panel method implementation and for a co-simulation environment is proposed. These reco...
