SUMMARY This paper reports on the application and development of a fully hyperbolic and fully conservative two-phase flow model for the simulation of gas and magma flow within volcanic processes. The model solves a set of mixture conservation equatio

A mathematical formulation is proposed for the solution of equations governing isentropic gas-liquid flow. The model considered here is a two-fluid model type where the relative velocity between the two phases is implemented by a kinetic constitutive

We propose a new model and a solution method for two-phase two-fluid compressible flows. The model involves six equations obtained from conservation principles applied to a one-dimensional flow of gas and liquid mixture completed by additional closur

Computational Fluid Dynamics (CFD) is becoming a tool that can be used by engineers to optimise valve performance. CFD is used here to model the fluid flow characteristics through a control valve. By changing various aspects of the internal flow path

The hydromagnetic spin-up and spin-down of an incompressible electrically conducting fluid on a heated infinite disk rotating in a vertical plane in the presence of a magnetic field and a buoyancy force have been studied. The flow is non- axisymmetri

The unsteady free convection boundary-layer flow in the forward stagnation-point region of a sphere, which is rotating with time-dependent angular velocity in an ambient fluid, has been studied. Both constant wall temperature and constant hear flux c

This work proposes a mixture model to simulate cavitating two-phase flows with velocity non-equilibrium using Godunov methods. As such, the model results are compared to those of test cases reported in the literature and validated against exact or ot

This paper presents further validation of previous works [1, 2] on simulating fully hyperbolic and fully conservative gas-solid mixture PDEs. Such a system allows non-equilibrium processes between the two phase systems and facilitates explosive volca

The problem of heat transfer in the unsteady free convection flow over a continuous moving vertical sheet in an ambient fluid has been investigated. Both constant surface temperature and constant surface heat flux conditions have been considered. The

Computations of gas-solid two-phase flow are carried out within the framework of mixture formulations. These computations are based on the Riemann problem for the resulting theoretical equations. The Riemann problem for the model equations is solved
