Abstract

 In this study, the effects of cavity
structures, which are located in different regions on NACA 0018 wing profile,
on the flow structure are investigated theoretically by using computational
fluid dynamics (CFD). These effects are applied for different attack angles on
the same wing profile with and without cavity. As a result of our analysis,
pathlines, velocity contours, pressure contours, velocity streamlines are drawn
for NACA 0018 wing profile with and without cavity, and compared with cavity
structures with and without intake system.

Oyuk Boşluk Yapısının Kanat Profili Üzerine Etkisi

Year 2019, , 89 - 105, 25.12.2019
https://doi.org/10.30518/jav.614043

Abstract

Bu çalışmada, NACA 0018 kanat
profili üzerindeki oyuk boşluk yapısının akış yapısı üzerine etkileri
hesaplamalı akışkanlar dinamiği (HAD) kullanılarak teorik olarak incelenmiştir.
Bu etkiler, boşluklu yapıya sahip olan ve olmayan aynı kanat profili üzerinde
farklı hücum açıları için uygulanmıştır. Analizlerimiz sonucunda, oyuklu ve
oyuksuz NACA 0018 kanat profili için yörünge çizgileri, hız konturları, basınç
konturları, hız akım çizgileri çizdirilmiş ve emme sistemi bulunan ve
bulunmayan boşluk yapılarındaki akım çizgileri ile karşılaştırılmıştır.
