What are the keystones of smooth particle hydrodynamics?
Best insight from top research papers
Smoothed Particle Hydrodynamics (SPH) is a mesh-free Lagrangian numerical technique widely used in various fields due to its ability to handle large deformations. Key aspects of SPH include efficient neighbor list implementation for high performance, the ability to simulate thin-film fluids with complex surface deformations and tangential flows, and its suitability for modeling wet granular materials by incorporating capillary interactions and cohesion effects. SPH's adaptability to scenarios with large deformation, free surface flow, and continuum mechanics problems makes it a versatile tool in astrophysics, fluid mechanics, and other disciplines. Additionally, SPH's compressible nature can be advantageous in co-evolving thickness, surface tension, and in-plane flows, enabling realistic simulations of various phenomena like vortical swirls and capillary waves.

Particle migration in the Pulsatile flow?4 answersParticle migration in pulsatile flow has been studied numerically in several papers. It has been found that the speed of axial migration of particles can be accelerated by flow pulsation at specific frequencies. The migration speed increases with the oscillatory amplitude, while the most effective frequency remains unchanged and independent of the amplitude. These studies have important implications for understanding cellular flow mechanics, as pulsatile flows are physiologically relevant in human circulation and can potentially affect the dynamics of deformable particles and red blood cells (RBCs). Additionally, the findings suggest that pulsatile flows can be potentially exploited in cell focusing techniques. The effects of Reynolds number and blockage ratio on particle migration in pulsatile flow have also been investigated, showing that the particle migrates back to the channel centerline with underdamped oscillation during the time period with zero-velocity. These studies contribute to understanding nanoparticle migration in arteries and have implications for applications involving periodic flow propagation and control.

Smoothed hydrodynamics particles in real time?5 answersSmoothed particle hydrodynamics (SPH) is a kernel-based discretization method for fluid-flow problems. Mathematical understanding of SPH is still limited. A code for weakly compressible SPH has been developed that is energy-preserving and globally time-reversible. The code achieves global-in-time reversibility by correcting the initial state, implementing a conservative fluid-wall interaction, and using fixed-point arithmetic. However, thermalization of particle velocities and growth of Boltzmann entropy are observed, leading to the emergence of irreversible behavior from purely reversible dynamics. The dynamics of a mixture of gas and multiple species of large dust grains can be simulated using SPH. The method captures the differential backreaction of multiple dust species on the gas, which is important for large dust-to-gas ratios in protoplanetary discs. The method has been benchmarked against analytic solutions and shown to be robust and accurate. SPH has been widely applied to astrophysics, and different numerical treatments have been evaluated for shock tube simulations, comparing the results with analytical solutions.
What is generalized hydrodynamics?5 answersGeneralized hydrodynamics (GHD) is a theoretical approach used to study the behavior of integrable and near-integrable quantum many-body systems out of equilibrium. It has been successfully applied to describe the dynamics of interacting one-dimensional Bose gases, such as the Lieb-Liniger model. GHD is based on the concept of local generalised Gibbs ensembles and provides a framework for understanding the large-scale dynamics of these systems. It has been shown that GHD equations can be derived from the microscopic dynamics of the system, without relying on the assumption of local entropy maximisation. This derivation has been achieved for the Lieb-Liniger model by considering a gas of wave packets formed by macroscopic-scale modulations of Bethe eigenfunctions. The classical dynamics of these wave packets gives rise to the GHD equations, allowing for a deeper understanding of the hydrodynamics of integrable models.
For modified Bessel function of the second kind, is this function smooth?5 answersThe modified Bessel function of the second kind is a smooth function. It has robust derivatives with respect to the smoothness parameter, which is of high interest in Gaussian processes modeling. The lack of robust derivatives of the modified Bessel function of the second kind with respect to order has been a challenge in differentiable optimization. However, newly identified series expansions for the modified Bessel function of the second kind have been proposed, which provide highly accurate results using the complex step method. Mean value inequalities and Turan-type inequalities have been established for the modified Bessel function of the second kind, which further demonstrate its smoothness and properties. Finite sum representation formulae have also been derived for the modified Bessel function of the second kind, indicating its smooth behavior.
How do the properties of a particle affect its motion in a fluid?2 answersThe motion of a particle in a fluid is influenced by its properties such as density, size, sphericity, shape, and physical strength. Heavier particles tend to have higher solids concentration laterally and axially, while larger particles result in more compact solids distribution, especially at the bottom of the riser. The shape and size of a particle affect its motion through factors such as drag force, interfacial area, and balance between forces like normal force, shear force, gravity, and surface tension. In non-Newtonian fluids, the rheological properties of the fluid, such as elasticity and shear thinning, also play a role in particle migration, with elasticity directing particles towards the centerline of the channel and shear thinning causing migration towards both the centerline and corners. Overall, the properties of a particle determine its behavior and response in a fluid environment, influencing factors like concentration, motion, and interaction with other particles.
