Design Algorithm of Flexible Propeller by Fluid-Structure Interactive Analysis

Fluid-structure interaction studies on marine propeller

Composite propellers offer high damping characteristics and corrosion resistance when compared with metal propellers. But the design of a hybrid composite propeller with the same strength of metal propeller is the critical task. For this purpose, the present paper focusses on fluid-structure interaction analysis of hybrid composite propeller with Carbon/Epoxy, R-Glass/Epoxy and S2-Glass/Epoxy t...

High Altitude Propeller Design and Analysis Overview

Simulation of fluid−flexible structure interaction

Systems involving flexible bodies interacting with surrounding fluid flow are commonplace, but are challenging to model numerically on account of their complex geometries and freely moving boundaries. In the present study, we developed an immersed boundary method (IB) for simulating fluid−flexible structure interactions. Our method is based on an efficient Navier-Stokes solver adopting the frac...

Quantitative Structure Activity Relationship Analysis of Coumarins as Free Radical Scavengers by Genetic Function Algorithm

The antioxidant properties of coumarin derivatives using the 2,2ˈ -diphenyl-1- picrylhydrazyl (DPPH) radical scavenging assay were investigated by the application of Quantitative Structure Activity Relationship (QSAR) studies. The molecular structures were optimized and submitted for the generation of quantum chemical and molecular descriptors. Genetic Function Algorithm (GFA) was employed in m...

Presenting a Modified SPH Algorithm for Numerical Studies of Fluid-Structure Interaction Problems

A modified Smoothed Particle Hydrodynamics (SPH) method is proposed for fluid-structure interaction (FSI) problems especially, in cases which FSI is combined with solid-rigid contacts. In current work, the modification of the utilized SPH concerns on removing the artificial viscosities and the artificial stresses (which such terms are commonly used to eliminate the effects of tensile and numeri...
