A Unified Mathematical Model for High Speed Hybrid (Air and Water-borne) Vehicles. [PDF]

open access: yes, 2007
During the last two decades, the interest in civil and military high speed marine vehicles has lead to several new configurations. Some of them exploit a combination of aerodynamic and hydrodynamic forces to sustain part of the weight of the craft ...

Relativistic hydrodynamics – causality and stability [PDF]

open access: yesThe European Physical Journal Special Topics, 2008
Causality and stability in relativistic dissipative hydrodynamics are important conceptual issues. We argue that causality is not restricted to hyperbolic set of differential equations. E.g. heat conduction equation can be causal considering the physical validity of the theory.

The concept of application of oscillation energy in modern technologies of directional drilling [PDF]

open access: yesE3S Web of Conferences, 2021
In the process of research, there was investigated the question of influence of rotary movement of washing fluid on hydrodynamic processes with the purpose of enhancement of its transportation properties, especially in the process of drilling of ...

multiobjective optimization in hydrodynamic stability control [PDF]

open access: yes, 2008
We focus on a shape optimization problem in hydrodynamic stability control. The goal is to minimize the drag in a flow regime by modification of the underlying geometry while ensuring hydrodynamic stability.

Vibrational Heat Transfer Intensification in an Annulus with a Deformable Boundary

open access: yesShock and Vibration, 2019
An experimental study is carried out on heat transfer in a horizontal liquid annulus at boundary oscillations. The inner boundary is formed by a copper rod that is heated using electric current.

A Review on Hydrodynamical Stability of Thin Film Flowing Along an Inclined Plane

open access: yesJournal of Mathematical Sciences and Modelling, 2019
The dynamics and stability of thin liquid films have fascinated scientists over many decades. Thin film flows occur over a wide range of length scales and are central to numerous areas of engineering, geophysics and biophysics. These include nanofluidics

Aerodynamic forces on high speed multi-hulled marine vehicles [PDF]

open access: yes, 2008
The need for high-speed high-payload craft has led to a considerable interest in vehicles capable of bridging the gap between conventional ships and aircraft. One such concept uses the forward motion of the craft to create aerodynamic forces on a wing-

Near-wall effects in rarefied gas micro-flows : Some modern hydrodynamic approaches [PDF]

open access: yes, 2007
Methods for simulating the critical near-wall region in hydrodynamic models of gas micro-flows are discussed. Two important non-equilibrium flow features - velocity slip at solid walls, and the Knudsen layer (which extends one or two molecular mean free ...

Destabilization of a laminar flow in a rectangular channel by transversely-oriented wall corrugation

open access: yesArchives of Mechanics, 2011
Linear stability of the flow through the transversely corrugated channel with flat sidewalls is investigated numerically. Two variants of the wall corrugation are considered: symmetric sinusoidal waviness of the top and bottom walls and onesided ...
