Abstract Recent years have witnessed a growth in mathematics for deep learning—which seeks deeper understanding of the concepts learning with and explores how to make it more robust—and mathematics, where algorithms are used solve problems mathematics. The latter has popularised field scientific machine is applied computing. Specifically, neural network (NN) architectures been developed specific classes partial differential equations (PDEs). Such methods exploit properties that inherent PDEs...
Impurities like air bubbles in hydraulic liquids can significantly affect the performance and reliability of systems. The aim this study was to develop a model suited for system simulation determine rate degassing dissolved micro-orifice flow at cavitating conditions. An existing through extended account generation vapor which is suggested play key-role mechanism. In comparison with measurements, results modeling approach imply that diffusive mass transfer into generated cavities dominating...
The paper deals with the study of source terms for Euler and Navier-Stokes equations which describe cavitation phenomena in one- three-dimensional flow. Cavitation occurs many technical applications, such as injectors, throttles pumps. modeling is a challenge due to complex structure process difficult numerical realization. main problem simulate or flow order predict material erosion determine mass will be limited if throttle.
The simulation of cavitation phenomena plays an important role for development modern hydraulic tools and injection systems. Cavitation leads to a reduction mass flow influences the wave motion in components significantly. article deals with homogeneous model based on thermodynamic properties liquid steam understand basic physical phenomena.
This study presents measurements on air release of V-oil 1404 in the back flow a micro orifice at choked conditions using shadowgraph imaging method. The released was determined three positions downstream for different pressure conditions. It found that more than 23% initially dissolved is and appears form bubbles.
Abstract This paper compares the accuracy and computational efficiency of fully explicit semi‐implicit 1D 2D finite volume schemes for simulation highly unsteady viscous compressible flows in laminar regime axially symmetric compliant tubes. There are essentially two main classes mathematical models that can be used to predict pressure velocity distribution along tube: one class is based on full Navier‐Stokes equations an geometry, leading a two‐dimensional governing PDE system with moving...
Formation of vapor and air bubbles in hydraulic liquids can lead to significant degradation the performance lifetime systems. Vapor cavities are generated due phase transition. vapor-air takes place diffusion dissolved gas molecules through bubble interfaces. The goal present study was formulate a mathematical model process high-speed unsteady liquid flows with cavitation. proposed is based on consideration driven by gradients concentration both pure liquid-vapor mixture. Convective...
The connection of Taylor maps and polynomial neural networks (PNN) to solve ordinary differential equations (ODEs) numerically is considered. Having the system ODEs, it possible calculate weights PNN that simulates dynamics these equations. It shown proposed architecture can provide better accuracy with less computational time in comparison traditional numerical solvers. Moreover, network derived from ODEs be used for simulation different initial conditions, but without training procedure....
Cavitation is a phenomenon of formation bubbles (cavities) in liquid as result pressure drop. plays an important role wide range applications. For example, cavitation one the key problems design and manufacturing pumps, hydraulic turbines, ship's propellers, etc. Special attention paid to erosion performance degradation devices (noise, fluctuation mass flow rate, etc.) caused by two phase system with increased compressibility. One more problem accompanying degassing due diffusion dissolved...
Cavitation is the reason for degradation of performance technical devices that involve high speed liquid flows. Detailed information on structure cavitating flow key importance design such devices.
