Abstract: Due to the negative correlation between pressure resistance and waterborne sound insulation, lowimpedance soundproof materials can hardly work in deep water. Here, we propose a new mechanism to circumvent this problem by ...

Abstract: Over the past two decades, the modeling of flow in a perforated pipe with influx through wall openings has been recognized as a key topic especially in the field of horizontal wells. In this paper, based on the theoretical ...

Abstract: A model of a parallel-type acceleration lane length based on the dynamic merging process is established in this study to determine the need for parallel-type acceleration lane length of merging vehicles. The model considers ...

Abstract: Acoustic metamaterial plays a vital role in underwater engineering applications. Here we present a novel tunable underwater metamaterial for ultra-broadband hydroacoustic focusing. The material consists of a soft matrix ...
