| Outline of Final Research Achievements |
Biofouling on ship’s hull causes increase of frictional resistance and fuel cost. In addition the fouling on ship’s hull may cause cross-border transfer of alien organism. To avoid such consequences, simple and low cost inspection technique to quantify the fouling is needed. Aimed at application to actual ship, detection method for biofilm adhesion was developed. The detection method is based on image analysis and applicable for transparent biofilm by using transmitted light in the film. Growth process of biofilm in an open channel was observed by in-situ measurement. It was shown that adhesion of biofilm is affected by flow field around the film.
