Abstract

método para gerar uma camada de bolhas em um casco de uma embarcação, e, embarcação. a invenção diz respeito a um método de gerar uma camada de bolhas em um casco de uma embarcação compreendendo as etapas de: prover uma cavidade no fundo da embarcação, com um comprimento de pelo menos 1 m e não mais que 30% do comprimento da embarcação l ao longo do fundo, preferivelmente não mais que 25 %, mais preferivelmente não mais que 10 % do comprimento da embarcação l, e com uma superfície superior espaçada pelo menos 50 cm do plano inferior, preferivelmente pelo menos 1 m no plano inferior; prover ar na cavidade por meio de um dispositivo compressor a uma pressão maior que a pressão atmosférica para esvaziar pelo menos parcialmente a água da cavidade; prover uma interface água-ar na cavidade para formar uma região de mistura; gerar uma pluralidade de bolhas de ar na região de mistura; e prover uma saída de bolhas na traseira da cavidade, ou próximo a ela, para permitir que as bolhas escoem para fora ao longo do casco em direção à traseira da embarcação.
