Abstract

Bu çalışmada Y-şeklinde katı damar modeli açık kaynak kodlu Salome program ile oluşturulmuş, stenöz gözlenen bir dalda akışkan-katı etkileşim analizi yapılmıştır. Hesaplamalı akışkanlar dinamiği analizleri OpenFOAM (foam-extend) kullanılarak gerçekleştirilmiştir. Akışkan için hem Newtonyen hem de Newtonyen olmayan akış modelleri kullanılmıştır. Hız girişi ise literatürden pulsatil bir çevrim olarak alınmıştır. Analiz sonucunda stenoz oluşmuş bölgede duvar kayma gerilmeleri ve duvar deformasyonu tespit edilmeye çalışılarak, stenoz olan bölgenin akış üzerindeki etkisi açıklanmıştır.

Fluid-Solid Interaction of a Stenosed Y-Shaped Vessel with OpenFOAM

Abstract

In this study, a Y-shaped solid vessel model was created with the open-source Salome program, and fluid-structure interaction analysis was performed in a branch with stenosis. Computational fluid dynamics analyzes were performed by using OpenFOAM (foam-extend). Both Newtonian and Non-Newtonian flow models are used for the fluid. The velocity input is taken as a pulsatile cycle from the literature. As a result of the analysis, the wall shear stresses and wall deformation in the stenosed region were tried to be determined, and the effect of the stenosed region on the flow was explained.
