Interference Effects in Multihull Configurations: A Systematic Review of Current Literature

Abstract

Multihull vessels are widely utilized in both commercial and naval applications, primarily due to their advantageous high deck-area-to-wetted-surface-area ratio. However, compared to conventional monohulls, the nonlinear interactions induced by multiple adjacent hulls advancing in a free surface significantly complicate their overall hydrodynamic behavior, ranging from resistance to seakeeping characteristics. This phenomenon, widely recognized in the literature as the interference effect, encompassing both wave and viscous interaction components, is comprehensively addressed in the present study. The primary objective of this paper is to provide a systematic literature review that elucidates how and through which computational and experimental methodologies this effect is investigated across various hydrodynamic problems. In this context, the results of the systematic review, conducted using Web of Science and Scopus databases, reveal that the interference effect is predominantly evaluated in terms of its impact on ship resistance, whereas its influence on seakeeping and manoeuvring characteristics has been investigated in a relatively limited number of studies.

Çok Gövdeli Gemi Yapılarındaki Girişim Etkisinin Güncel Literatürdeki Yeri Üzerine Sistematik Bir İnceleme

Abstract

Çok gövdeli gemiler, temel olarak yüksek güverte alanının ıslak yüzey alanına oranının sağladığı avantaj nedeniyle hem ticari hem de askeri uygulamalarda yaygın olarak kullanılmaktadır. Ancak, geleneksel tek gövdeli gemilerle karşılaştırıldığında, serbest su yüzeyinde ilerleyen birbirine yakın birden fazla gövdenin indüklediği doğrusal olmayan etkileşimler, bu gemilerin dirençten denizcilik özelliklerine kadar uzanan genel hidrodinamik davranışını önemli ölçüde karmaşıklaştırmaktadır. Literatürde yaygın olarak girişim etkisi adıyla bilinen ve hem dalga hem de viskoz etkileşim bileşenlerini barındıran bu olgu, bu çalışmada kapsamlı bir şekilde ele alınmaktadır. Bu makalenin temel amacı, söz konusu etkinin çeşitli hidrodinamik problemlerde hangi hesaplamalı ve deneysel yöntemler aracılığıyla nasıl incelendiğini aydınlatan sistematik bir literatür taraması sunmaktır. Bu bağlamda, Web of Science ve Scopus veri tabanları kullanılarak gerçekleştirilen kapsamlı sistematik incelemenin sonuçları; söz konusu girişim etkisinin ağırlıklı olarak gemi direnci üzerindeki doğrudan etkisi açısından değerlendirildiğini, dinamik denizcilik performansı ve manevra karakteristikleri üzerindeki bütüncül etkisinin ise güncel literatürde görece çok daha sınırlı sayıda çalışmada incelendiğini açıkça ortaya koymaktadır.
