翼滑艇水动力特性研究

翼滑艇是江苏科技大学提出来的一种新型高速船。三是综合了滑行艇和水翼艇的性能而得到的一种新型复合船型,是以滑行艇的滑行面作为船体,而在首部安装水翼。。这样水翼可以提供支撑船体的升力,有助于减小滑行艇的海浪拍击、提高船体的稳定性,同时在翼航状态时,相比较水翼艇来说,部分船体在水下,其操纵性得到了改善。本书利用实验和数值计算的方法对翼滑艇的水动力特性进行了初步研究。内容包括水翼艇及机翼理论、滑行艇水动力特性实验研究、翼滑艇水动力特性实验研究、高速船水动力特性数值研究实现、网格依赖性和计算域尺寸研究、滑行艇水动力特性在定常流动中的数值研究、翼滑艇水动力特性在定常流动中的数值研究、翼滑艇水动力特性在非定常流动中的数值研究等。
