Write some info about fluid?5 answersFluids are substances that can flow and take the shape of their container. They include liquids, gases, vapors, and plasmas, with some plastic solids also exhibiting fluid-like behavior. In fluid mechanics, infinitesimal masses called fluid parcels occupy defined volumes in space, behaving similarly to point masses in classical mechanics. Fluid mechanics studies the properties and behavior of fluids, including their transport properties and dimensionless numbers commonly used in the field. Computational methods in fluid research have advanced significantly, with artificial intelligence and machine learning playing a crucial role in extracting knowledge from data generated through simulations and experiments, particularly in predicting fluid properties with high accuracy.
How can fluid dynamics be expressed by Hamiltonian formalism?4 answersFluid dynamics can be expressed using Hamiltonian formalism. Traditionally, Hamiltonian formulations have been used in classical and quantum mechanics, offering a new perspective and powerful tools like conservation laws and stability theorems. However, it was only recently that Hamiltonian formulations were introduced into fluid-flow problems. This is because the Eulerian variables in fluid-flow problems are non-canonical, making it challenging to relate them to Lagrangian variables through a canonical transformation. Lagrangian variables, on the other hand, follow Hamilton-like equations and possess additional particle-relabelling symmetries. By translating the Lagrange equations into Hamilton equations, a set of first-order ODEs can be obtained, which are more useful in studying fluid dynamics. The Hamiltonian structure of fluid dynamics has also been studied in the context of relativistic field theory, where the conservation of the stress tensor is explicitly verified.
How does fluid dynamics affect the behavior of biological systems?4 answersFluid dynamics plays a crucial role in the behavior of biological systems. It influences cells in suspension, such as red and white blood cells, as they pass through microchannels in the cardiovascular and lymphatic systems. These cells are subject to complex fluidic forces that can affect processes like infection spreading, cancer metastasis, and cell viability. Fluid dynamics also affects the locomotion of cells like bacteria and spermatozoa, which possess flagella that generate motility through time periodic motion in a fluid environment. Furthermore, fluid-dynamic stimuli can modulate the behavior of various cell types, including epithelial cells, smooth muscle cells, fibroblasts, articular chondrocytes, and bone cells. These stimuli can influence cell alignment, proliferation, differentiation, migration, and cytokine secretion, impacting the physiological functions of tissues and the development and progression of diseases. Understanding the effects of fluid dynamics on biological systems is crucial for predicting, diagnosing, and correcting biological dysfunction, as well as inspiring new engineering technologies.
How does fluid dynamics in the arterial system affect the flow of blood?5 answersFluid dynamics in the arterial system has a significant impact on the flow of blood. The flow in arteries is pulsatile and nonuniform, with secondary flows generated at curves and branches. These flow characteristics can lead to the development of atherosclerosis, as plaque tends to localize in areas of low and oscillating wall shear stress. The motion of the vessel wall, driven by the pressure pulse, also influences the local flow fields. It can have a dominant effect on mean pressure gradient and a significant effect on mean wall shear stress. Additionally, the non-Newtonian nature of blood affects the flow field, particularly in regions of flow separation. Overall, understanding the fluid dynamics in the arterial system is crucial for diagnosing health problems, predicting thrombosis, and designing medical devices.
What is fluid?2 answersA fluid is a substance that flows without disintegration when pressure is applied. It includes gases, liquids, and certain solids. Fluids can be used in food processing and exhibit resistance to flow similar to liquids. Fluids are chemically inert and electrically non-conducting materials. They can be liquids or supercritical gases, such as liquid nitrogen or supercritical/liquid carbon dioxide, at pressures higher than 1 bar. They are used to create dry products by evaporating the gas after mixing with solid particles. Fluids are substances that flow under the action of a shear stress, regardless of how small the shear is. They can quickly assume the shape of the container they are placed in. Both liquids and gases fall within the purview of fluid mechanics. Fluids are materials that deform continually under the application of an external force. They can flow and do not have a rigid three-dimensional structure. An ideal fluid is one in which there is no friction.
What is computational fluid dynamics?5 answersComputational Fluid Dynamics (CFD) is a rapidly developed computational modelling approach that aims to numerically generate solutions for fluid flows and heat transfer. It is a numerical technique primarily used to solve physical flow situations with complex geometry and/or boundary conditions. CFD is essential for solving modern fluid mechanical problems that cannot be solved analytically due to limited scope and difficult geometries. The technique involves various numerical methods such as weighted residual methods, spectral methods, Finite Difference Method (FDM), Finite Volume Method (FVM), and Finite Element Method (FEM). These methods vary in their general applicability, robustness, and computational cost, with FEM being the most widely applicable and robust method. CFD also involves the use of turbulence models to simulate turbulent flows and is applied in various fields, including wind turbine simulations. Overall, CFD is a powerful tool for obtaining numerical solutions to fluid flow problems with complex geometries and boundary conditions.
