Abstract
Water accumulating in the fuel tanks of any aircraft presents an unacceptable safety hazard. This accumulation, which is due to a combination of physical phenomena, is difficult to assess and therefore not well known. The purpose of this project is the development of a lightweight computational prediction method for water accumulation in helicopter fuel tanks. This model delivers a better understanding of the physical mechanisms involved and allows prediction of the accumulated water quantity under given conditions.
