Particle erosion from slurry flow is a common problem in many industrial applications, including the mining and the oil and gas industry. Erosion modelling is a known complex problem, and consists of three equally important parts; fluid flow modelling, particulate flow modelling, and erosion modelling. It is the first of these, the fluid flow, which is analysed here. The paper compares three di...

Information of traffic condition in cities is hardly obtainable by road users and operators. In this paper, a new developed microscopic traffic simulation model is proposed, which can be used for several purposes. This novel traffic simulation model is based on a well known efficient and highly realistic traffic flow model. A new approach of an alternative departure time model using a combinati...

in the present study, a heterogeneous and homogeneous gas flow dispersion model for simulation and optimization of a large-scale catalytic slurry reactor for the direct synthesis of dimethyl ether (dme) from synthesis gas (syngas) and co2, using a churn-turbulent regime was developed. in the heterogeneous flow model, the gas phase was distributed into two bubble phases including small and large...

In this paper, a system for efficient removal of carbon dioxide by hollow fiber membranes is proposed. The system is compact, and it is very useful for application in the offshore energy industries. In particular, it is used to removing CO2 from the exhaust of power generation facilities on offshore platforms.The proposed dual membrane contactor contains two types of membranes (polypropylene me...

This paper describes a simple and deterministic method for modelling and designing a flow manufacturing system, especially well suited for SMEs. The paper covers five themes: A brief review the history of flow manufacturing, a comparison of the flow manufacturing approach with other existing improvement approaches, a proposal of crucial design principles for flow manufacturing, a method for sim...

Scanning Ion Conductance Microscopy, it’s development, design and use are introduced. The theory behind modelling ion current flow into the SICM probe tip and the problems involved with analytically modelling the current flow are then briefly discussed. A numerical simulation using the Finite Difference Method is then used to model the current flow as the microscope probe tip approaches a flat ...
