Khush Bakhat Rana, Božidar Šarler
Doktorska disertacija
Oznake: dissertations;computational fluid dynamics;two-phase gas-liquid flow;compressible flow;phase-field method;meshless method;diffuse approximate method;PISO algorithm;gas-focused micro-jet;
The meshless diffuse approximate method and phase-field method have been combined to simulate compressible two-phase gas-liquid flow problems. The gas and the liquid behave in a Newtonian way. The model employs coupled mass, momentum, energy, equation of state and Cahn-Hilliard equations. The Navier ...

The interface between two immiscible Newtonian liquids with different densities and the same viscosity, influenced by gravity, is based on the Phase-Field Method (PFM) formulation. The solution of the related governing coupled Navier-Stokes (NS) and Cahn-Hillard (CH) equations is structured by the m ...

ǂA ǂCFD study on optimization of mass transfer and light distribution in a photocatalytic reactor with immobilized photocatalyst on spheres
Qasim Jamil, Khush Bakhat Rana, Lev Matoh
Izvirni znanstveni članek
Oznake: fotokataliza;optimizacija zasnove reaktorja;AOP-ji;analiza CFD;stekleni biseri;photocatalysis;reactor design optimization;AOPs;CFD analysis;glass beads;
This study explores the influence of flow velocity, sphere size, and inter-sphere distance on hydrodynamics and mass transfer in a photocatalytic reactor. The effects of two different light configurations on light distribution and degradation were also evaluated. A 2D computational fluid dynamics (C ...

ǂA ǂmeshless solution of the compressible viscous flow in axisymmetric tubes with varying cross-sections
Khush Bakhat Rana, Boštjan Mavrič, Rizwan Zahoor, Božidar Šarler
Izvirni znanstveni članek
Oznake: compressible flow;ideal gas;axisymmetry;diffuse approximate method;PISO;
The meshless Diffuse Approximate Method (DAM) is for the first time formulated and applied to simulate the compressible Newtonian flow of an ideal gas in an axisymmetric tube with varying cross-sections. The problem is structured by coupled partial differential equations for conservation of mass, mo ...

Oznake: two-phase flow;phase-field;two-dimensionality;axisymmetry;diffuse approximate method;PISO;
A formulation of the immiscible Newtonian two-liquid system with different densities and influenced by gravity is based on the Phase-Field Method (PFM) approach. The solution of the related governing coupled Navier-Stokes (NS) and Cahn-Hillard (CH) equations is structured by the meshless Diffuse App ...
