Discrete Vortex Prediction of Flow around Two Cylinders in Side by Side using Simple Grid System
Journal Title: American Journal of Engineering and Applied Sciences - Year 2017, Vol 10, Issue 2
Abstract
Abstract Modelling of flows around two cylinders in side by side arrangement using a simple overlapping grid system is carried out. The use of such grid system is intended to give a considerable reduction in terms of the CPU time, especially during the calculation of the vortex velocity. It has been shown that this method is not only time efficient, but also gives a better distribution of surface vorticity as the scattered vortices around the cylinder are now concentrated on grid point located at uniform distance from the cylinder. The engineering applications of this topic is to simulate the loading on structural elements due to the presence of anodes. The in-line and transverse force coefficients and the flow patterns obtained are presented in order to provide more detail description of the flow phenomena and interaction involved. The comparison of the results with both experimental and numerical evidence is also presented and the range within which the algorithm produces good results is identified.

Stochastic Model for Variable Amplitude Fatigue Induced Delamination Growth in Graphite/Epoxy Laminates
Abstract A stochastic model is used to predict the growth of delamination in graphite/epoxy laminates subjected to variable amplitude cyclic loading. The advantage of this model is that both the mean and variance associ...
