Significant submarine mineral deposits form when hot, metal-laden, saline fluids emerge onto the seafloor and mix with ambient seawater. Resulting density changes of fluid mixtures can trigger fluid buoyancy reversals, brine pool formation, and metal accumulation (Figure 1). While some ... 詳細を見る

The flow morphology of two immiscible fluids in a microfluidic device finds numerous applications such as emulsification, synthesis of nanomaterials [1], lab-on-a-chip devices and biological analysis [2]. It offers many advantages over the conventional macroscopic devices because of its ... 詳細を見る

Insulator-based dielectrophoresis (iDEP) employs arrays of electrically insulator posts in a microfluidic device to create dielectrophoretic forces that affect particle movement (Figure 1). The trapping performance of iDEP devices involves a careful balance between electrokinetics (EK) ... 詳細を見る

Acoustic streaming (AS) describes a physical phenomenon where an oscillating sound emitter induces a steady fluid motion. Metal processing industry applies this treatment for grain morphology adjustments during the solidification of metal. Improvement and further development of this ... 詳細を見る

In our study of chaotic mixing, 3D velocity measurements (u,v,w) are required for evaluation of a micro mixer using a mix-prediction algorithm. The hybrid approach presented here combines 2D measurements, an imperfect numerical model, and appropriate fitting parameters. Because our ... 詳細を見る

The Microwave Electrothermal Thruster (MET) is a space electric propulsion device that uses an electromagnetic resonant cavity within which a free-floating plasma is ignited and sustained, heating a propellant gas that is that exhausted out of a gas-dynamic nozzle. For an empty cavity ... 詳細を見る

Hyperloop is a theoretical high-speed mass transportation system which aims to increase efficiency through the use of low-pressure tunnels and contactless propulsion. The University of Edinburgh’s Hyperloop Team (HYPED) has been selected to participate in the SpaceX Hyperloop Pod ... 詳細を見る

In this work, we present a number of scoping calculations that have been carried out to design an in-situ redox experiment (Figure 1) focused on assessing potential changes in the pH and redox conditions and in the buffering capacity of the Olkiluoto bedrock (i.e. the site for the ... 詳細を見る

The effect of finite boundaries on the drag experienced by a rigid sphere settling along the axis of cylindrical tubes filled with Carreau model fluids has been examined systematically over a wide range of condition. As expected, the presence of finite boundaries leads to an increase in ... 詳細を見る

The modeling of sublimation form a rotating cylinder of solid naphthalene in a confined vessel has been performed by coupling the model of incompressible Newtonian fluid flow with the model of the dilute solutions. Preliminary a 2D axisymmetric system with swirl flow function for laminar ... 詳細を見る
