Numerical investigation of interference effects for the Delft 372 catamaran
Due to interference effects, the resistance of a catamaran is not the same as the double resistance of the monohull. If demihulls are close enough to each other, the wave fields generated by each demihull usually significantly interfere causing either advantageous or disadvantageous effects. In this paper, the numerical investigation of interference effects for the Delft 372 catamaran is performed. The verification and validation studies are performed demonstrating the potential of the proposed numerical model for the analysis of interference effects. The investigation of the effect of Froude number and demihull separation on the total resistance of a catamaran, trim angle, and sinkage is conducted. The interference effects are quantified through the interference factor, which is defined based on the total resistance of a catamaran and double the total resistance of the monohull. Finally, the flow field characteristics, wave patterns, and pressure distributions are analysed using Computational Fluid Dynamics.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
