Abstract:

Recent efforts on the decarbonization, autonomy, and safety of the maritime vehicles required comprehensive analyses and prediction of the behavior of the existing vessels and prospective adaptations. To predict the performance of vessels, a better understanding of ship hydrodynamics is necessary. However, it is necessary to conduct dozens of experiments or computational fluid dynamics simulations to characterize the hydrodynamic behavior of the vessels, which require significant amounts of cost and time. Thus, system identification studies to characterize the hydrodynamics of ships have gaine

Abstract:

One of the most important tasks of underground hydrodynamics is the creation and development of methods for determining reservoir properties of oil and gas reservoirs. Hydrodynamic methods of studying formations and wells make it possible to obtain filtration and reservoir parameters of the formation, on the basis of which production processes are designed and carried out, an analysis of field development is carried out.

Fish-like robot is a special autonomous underwater vehicle with broad application prospects. Some previous studies concentrated on the hydrodynamics of free-swimming fish-like robots. But the hydrodynamic performance of fish-like robot swimming with a tilt angle in constrained space has not been well studied, and the influence of environmental wave and current on its is also still unclear. In this paper, the experiment devices, including a physical fish-like robot, a hydrodynamics measurement platform, and a six-axis force sensor, are used to study the effect of attack angle and environmental

Abstract:

The article addresses the issue of calculating the movement, flow and hydrodynamic qualities of twisted ropes. The external form of twisted ropes varies depending on the conditions under which it must be operated. For the correct choice of twisted ropes, experimental studies are carried out on special installations, as well as using computer simulations. The determining hydrodynamic coefficients of twisted ropes are the resistance force coefficient, the passport (deepening) force coefficient and the lateral force coefficient. Computer modeling of twisted ropes is beginning to be widely used to

This has led the authors to hybridize the permanent magnet with hydrodynamic technology and to explore the possibility of achieving the low starting t

Masonry arch bridges form an essential part of existing transport infrastructure around the world, including mainland Europe and the northeastern US. Recent extreme flood events highlight that masonry arch bridges spanning watercourses are vulnerable to flood-induced hydrodynamic and debris impact loads.

This paper presents both experimental and numerical studies to investigate this complex phenomenon, including fluid–structure and structure–structure interaction

Abstract:

Hydrodynamic Analysis of Trimaran Vessels Trimaran vessels are developed for different applications and hydrodynamic behavior of such vessels is different than usual mono-hulls. In this paper hydrodynamic resistance and maneuvering of a trimaran with Wigley body form are investigated. The effects of outriggers position in four different longitudinal and two transverse locations are studied. For hydrodynamic simulations a CFD code has been developed and used. This code is capable for simulating three dimensional, time dependent, two phases, viscous flow coupled with rigid body motion. Formulati

Abstract:

The issue is devoted to theoretical, computer and experimental studies of internal heterogeneous patterns, their morphology and evolution in various soft physical systems—organic and inorganic materials (e.g. alloys, polymers, cell cultures, biological tissues as well as metastable and composite materials). The importance of these studies is determined by the significant role of internal structures on the macroscopic properties and behaviour of natural and manufactured tissues and materials. Modern methods of computer modelling, statistical physics, heat and mass transfer, statistical hydrodyn

Abstract:

Introduction and Objective: Evidence demonstrates that there are many errors and misconceptions on fluid therapy. Starling’s law underlies it all. This report gives the complete evidence that Starling’s law is wrong on both forces and the correct replacement is hydrodynamic of the G tube. New physiological evidence is provided with clinical relevance and significance. Material and Methods: The physics proof is based on G tube hydrodynamic. The physiological proof is based on a study of the hind limb of sheep: running plasma and later saline through the artery compared to that through the vein

Abstract:

Low-crested (LC) rubble mound breakwaters are used for coastal protection. The main advantage of these structures is their mild aesthetic impact on the natural environment. As the waves approach and transmit over these structures, significant hydrodynamic processes occur in their proximal area, such as wave breaking, wave reflection, wave overtopping and transmission (Garcia et al., 2004). Many researchers have studied the hydrodynamics of flow in the vicinity of such structures, as well as the influence of their geometrical characteristics on the flow field. However, in most studies, the stru

Abstract:

The purpose of the article is to develop the required and sufficient conditions under which numerical methods can be used for engineering calculations and for scientific research of hydrodynamic processes in solving practical problems related to surveying of pollutants diffusion in water flows. The conducted studies consisted in the finding out conditions under which mathematical modelling using hydrodynamic equations allows to solve engineering problems of channel hydrodynamics and, in particular, to numerically simulate the transport of suspended particles in channels.
