The CFD modelling of metals reduction processes particularly always seems to involve the interaction of liquid metals, a gas (often air) top space, liquid droplets in the top space and injection of both solid particles and gaseous bubbles into the bath. These phases all interact and exchange mass, momentum and energy. Often it is the extent to which these multi-phase phenomena can be effectivel...

The gas holdup and flow dynamics in a laboratory scale Rushton-turbine flotation tank were simulated using the dispersed k- turbulence model and Eulerian-Eulerian multiphase modelling approach. The inherent uncertainties in the CFD predictions were quantified by examining the model and numerical (i.e., discretization) uncertainties. The contribution of model uncertainty was explored by conside...

Objectives 1. To identify organisations involved in gas explosion research in the U.K. and Europe. 2. To survey these organisations, to determine their areas of current and proposed work. 3. To collate their responses in a report, which also provides an up to date literature review of gas explosion modelling. 4. To critically assess the strengths and weaknesses of available gas explosion models...

Water disinfection is an essential process for drinking water use. One of the treatment stages includes application Ultraviolet (UV) light to assist with removal pathogens and viruses such as Cryptosporidium. The previous review in UV system explores optical reaction microorganisms technology. aim this paper explore hydraulics modelling current technology process. There has been enormous progre...

The advanced validation of a CFD code for containment applications requires the investigation of water steam in the different flow types like jets or buoyant plumes. This paper addresses therefore the simulation of two “HYJET” experiments from the former Battelle Model Containment by CFX. These experiments involve jet releases into the multi-compartment geometry of the test facility accompanied...

Spray ignition and flame stabilisation in the frame of diesel-like combustion conditions combine fundamental and complex physical and chemical processes. In this work, a numerical investigation has been performed to evaluate the potential of integrating detailed chemistry into CFD calculations, in order to improve predictions and gain more insight in involved processes. This work has been carri...

In the current era of globalization every prosperous nation in this world wishes to develop a fast moving aircraft with a high lift coefficient and low drag coefficient, which helps them to enhance their military force and strengthens its civilization’s foundation. The purpose of this study is to examine the viscous, incompressible and steady-state flow over the F-16 aircraft using computer mod...

Emergency smoke ventilation for a uni-directional traffic road tunnel is studied using a CFD modelling approach. Fire scenarios in an uphill ramp for congested traffic conditions have been considered. Based on a longitudinal smoke ventilation system with a damper smoke-extraction device on the ceiling soffit, the impact of longitudinal ventilation (LV) control, operation of fire suppression int...

An Intelligent Condition Monitoring System (ICMS) is important for different types of vehicles used to perform unmanned tasks. The main function of the ICMS is to ensure that the unmanned vehicle is in robust condition. In this paper, three main sections are built in ICMS. That is, structure health monitoring, power management and speed detection. For the structure monitoring, the pressure dist...
