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

Background: Even though the direct nose-to-brain drug delivery has multiple advantages, its application is limited by the low delivery efficiency (<1%) to the olfactory region with standard nasal devices. Novel delivery techniques are needed that can deliver clinically relevant dosage ... 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

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

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

We present COMSOL-based analyses and design optimizations of a micromachined wind sensor. The sensor relies on eight germanium thermistors embedded in a thin silicon nitride membrane, where two orthogonally arranged ensembles, each consisting of four thermistors, are connected to form a ... 詳細を見る

This work presents the results of a 3D numerical magneto-hydrodynamic (MHD) simulation of an electromagnetic DC pump for liquid metal using a rectangular metal flow channel subjected to an externally imposed transversal inhomogeneous magnetic field. In this study. 3D numerical simulation ... 詳細を見る

Numerical simulations applied to blood flow together with the imaging processing advances are a powerful tool in the prevention and treatment of some diseases. The inclusion of real data in the numerical blood flow simulations allows the achievement of more realistic and accurate ... 詳細を見る
