This paper is first of the two papers dealing with nonlinear modelling and investigation coupled cross-flow in-line vortex-induced vibrations (VIVs) flexible cylindrical structures. As a continuation previous work (Qu Metrikine in Ocean Eng 196:106732, 2020) where new single wake oscillator model was proposed studied for VIVs rigid cylinders, present focuses on applying it to cylinders. In this...

Phthalates are esters of phthalic acid, mainly used as plasticizer in polymeric packaging materials. The main objective of this research was to determine the exact roots of the phthalate esters in the Iranian flexible/laminated packaging films commercially used for food products such as ketchup, spaghetti, mayonnaise, black tea and snack foods. This investigation was carried out by analyzing th...

In the present study, an immersed boundary (IB) method for the simulation of flow around a thin flexible body is presented. The present method is based on a discrete-forcing immersed boundary method proposed by Kim et al. (JCP, 2001). The dynamic equation for a thin flexible body is coupled with the incompressible Navier-Stokes equations. With the proposed method, we simulate several flow probl...
