Due to the maneuver and overload requirements of aircraft, it is inevitable that supersonic fins experience high angles of attack (AOAs) and viscous effects at high altitudes. The local piston theory with viscous correction (VLPT) is introduced and modif...

Evaluating the structural safety and seakeeping performance of very large floating structures (VLFS) using the rigid module flexible connector (RMFC) method remains challenging due to the complexity of the coupled hydrodynamic?structural responses in thi...

The internal flow in a vertical axial-flow pump is a complex unsteady three-dimensional viscous flow. An unstable flow often produces complex flow phenomena such as flow separation, vortices, and secondary reflux, which reduces the operating efficiency o...

Modeling free surface flows in a CFD context typically requires an incompressible approach along with a formulation to account for the air?water interface. Commonly, pressure-correction algorithms combined with the Volume of Fluid (VOF) method are used t...

Partendo da un?analisi del debito di Sylos Labini (2003) e Pasinetti (1998), il presente articolo re-esamina criticamente le raccomandazioni di politica economica suggerite dalle teorie che scoraggiano l?intervento dello stato e sostengono l?austerità, i...

Viscous drag, nonlinear in nature, is an important aspect of the fluid?structure interaction modelling and is usually not taken into account when the fluid is assumed to be inviscid. Potential flow solvers can competently compute radiation damping, which...

A computational methodology for the hydrodynamic analysis of horizontal axis marine current turbines is presented. The approach is based on a boundary integral equation method for inviscid flows originally developed for marine propellers and adapted here...
