SERBEST SU YÜZEYİNE YAKIN DERİNLİKTEKİ DENİZALTININ MANEVRA SORUNLARININ İNCELENMESİ

Year 2023, Issue: 23, 55 - 65, 31.07.2023

Abstract

Gizlilik, denizaltıların en etkili özelliklerinden birisi olup; periskop derinliğinde bu özelliğini kaybetmeden görevlerini icra etmesi gerekmektedir. Ancak denizaltıların sahip olduğu form nedeniyle serbest su yüzeyine yakın derinlikte oluşan basınç dağılımı denizaltıyı başlı bir şekilde dalma yönünde harekete zorlamaktadır. Bu durumu nümerik olarak incelemek maksadıyla DARPA SUBOFF AFF-8 geometrisi ile OpenFOAM açık kaynak kodlu yazılımın çok fazlı akış çözücüsü kullanılmıştır. Ağ yapısı olarak da oluşturulan model, akış hacminden bağımsız dinamik hareket edebilen ‘overset’ hacmine yerleştirilmiştir. Oluşturulan ağın Hesaplamalı Akışkanlar Dinamiği (HAD) analiz sonuçlara etkisinin olup olmadığını incelemek maksadıyla da ‘Ağ Yakınsaklık İndeksi’ hesaplamalarıyla doğrulama çalışması yapılmıştır. Analiz sonuçlarında çapının 1,1 katı derinliğe yerleştirilen model, 0 (sıfır) derece açı değerinde bulunan dümenleri ve baştan 2,009 metre olarak belirlenen ağırlık merkezi ile başlı bir şekilde dalma hareketini yapmıştır. Bu manevra sorununu giderebilmek için ufki dümenlere aşağı yönde açı vermek ve baş taraftan balast atmak denizaltıcıların uyguladığı yöntemler olduğu öğrenilmiştir. Gelecek çalışmalarda bu çözümlerin etkisi parametrik olarak incelenecektir.
