Antifouling Boyaların Hidrodinamik Özellikleri Üzerine Bir HAD Çalışması

Öz:
Bu çalışmada, çeşitli antifouling boyaların hidrodinamik performanslarını incelemek için kullanılabilecek birhesaplamalı akışkanlar dinamiği (HAD) yaklaşımı sunulmaktadır. Düz bir levhanın etrafında gelişen, Reynoldssayısı 2,8×106 ve 5,5×106 olan akışları modellemek üzere, zamandan bağımsız zaman ortalamalı Navier Stokes(RANS) denklemleri çözülmüştür. Yüzey pürüzlülüğünün etkileri, sınır tabakanın logaritmik yasa bölgesindeki hızprofilinde aşağı kayma olarak modellenmiştir. Tam ölçekli bir gemiye ait sürtünme direnci sonuçlarını tahminetmek üzere Granville’nin benzerlik yasasından faydalanılmıştır. Sonuçlar daha önceki deneysel ve sayısalçalışmalar ile uyum içerisindedir.
Anahtar Kelime:

A CFD Study On the Hydrodynamic Characteristics of the Antifouling Paints

Öz:
This paper presents a computational fluid dynamics (CFD) approach which can be used to investigate the hydrodynamic performances of various antifouling paints. Steady Reynolds - Averaged - Navier - Stokes (RANS) equations were solved for the flows around a flat plate at Reynolds number of 2,8×106and 5,5×106 . The surface roughness effects were modelled as downward shift of the velocity profile at the log – law region of the boundary layer. Granville’s similarity law was used to extrapolate the results for a full scale ship. Results are in good agreement with the previous experimental and numerical studies.
