Partial depletion of the primary circuit during a postulated small break loss of coolant accident can lead to the interruption of one-phase flow natural circulation. In this case, the decay heat is removed from the core in the reflux-condenser mode. In case of the partial non-availability of the safety injection system, weakly borated condensate can accumulate in particular in the pump loop sea...
A novel approach of simulating hydromechanical coupling in pore-scale models of porous media is presented in this paper. Parameters of the sandstone samples, such as the stress-strain curve, Poisson's ratio, and permeability under different pore pressure and confining pressure, are tested in laboratory scale. The micro-CT scanner is employed to scan the samples for three-dimensional images, as ...
Abstract The main objective of this paper is to evaluate the aerodynamic performance a modified blended wing-bodied re-entry vehicle by computational fluid dynamics. This analysis examines airflow properties like pressure, density, and temperature under hypersonic flow. study wing model at different Mach speeds angles attack also included in research paper. All simulations are performed using d...
The design of high-speed railway lines (HSR) requires mandatory consideration loads from the aerodynamic interaction a moving train, air environment and infrastructure facilities, acting both on structures train itself. Software systems computational fluid dynamics are most expedient to determine nature intensity load. To find optimal approach modelling processes between environment, as well as...
Turbulence analysis of flow inside a hydrocyclone is carried out using commercially available CFD software ANSYS-CFX (release 11.0). Commercial CFD software(s) and their turbulence models have come a long way in accurately predicting the flow inside a hydrocyclone, both at the mean as well as at the turbulence level. Previous studies have shown, the more accurate the turbulence prediction is, t...
This thesis details the process taken for the computational modelling of convective heat transfer in porous media with the objective of improving the accuracy of porous continuum models. CFD simulations were performed to predict convective heat transfer resulting from forced flow through highly conductive porous blocks. For the pore-level predictions, an idealized geometric model for spherical-...
One challenge for the numerical simulation of a dry scroll vacuum pump is the discretization of the chamber volume, which changes with time. In addition, the flow characteristics are very complex including the leakage flow caused by radial and axial gaps between the rotors and the housing. For engineers and designers it is imperative to understand the influence of such leakage flows on the effi...
This study explores the numerical optimization of water turbine runner profile performance using a surface vorticity model algorithm. The is designed on laboratory scale and operates at net head 0.09 m, 400 rpm, flow rate 0.003 m3/s. initial design was optimized to minimize losses in hydrofoil. algorithm coded MATLAB software obtain optimal stagger angle that will be used design. Furthermore, v...
Currently, among the most popular computational fluid dynamics software packages are commercial CFD – ANSYS CFX, Fluent, STAR-CCM+ and several others. In contrast to above-mentioned packages, there is an OpenFOAM, a non-commercial, freely distributed, integrated platform for numerical modeling of solid-state mechanics tasks (including tasks), it becoming more popular. addition being non-commerc...
