Investigation of Transport Phenomena in Nanochannels and its Applications in Energy Conversion using COMSOL Multiphysics
Green Energy and Environment Research Laboratories, Industrial Technology Research Institute, Chutung, Hsinchu, Taiwan
Well‐designed and controlled nanochannels are ideal physical modeling systems to study fluidics in a precise manner. Electrokinetics refers to transport phenomena related to the non‐electroneutral EDL, which is created to neutralize the surface charges produced on surface. Surface charges are produced by the dissociation of surface functional groups. We created a mathematical model of a ...

Implantable biosensors have the potential to revolutionize the healthcare industry by allowing patients and their health care providers to continuously monitor blood pH levels, pCO2, proteins, metabolites, and a wide variety of other biomolecules. These devices need to operate completely wirelessly to be used for long term monitoring. Metal coils are attractive candidates for wireless power ...

Fuel bundles in the CANDU (CANada Deuterium Uranium) reactor are designed for heating a pressurized coolant (heavy water) to generate electricity. The designs for the fuel bundles differ based on the number of heating elements. The flow of heavy water over the elements and inside the shell is highly turbulent. In this paper, COMSOL Multiphysics® is used to simulate the heavy water flow ...

In this project, we attempted to determine the drug concentration in a breast cancer tumor after a drug has been delivered. We created a COMSOL Multiphysics® finite element model. We investigated the relationship between drug delivery efficiency and parameters such as diffusivity, deepness of the tumor, and the temporal and spatial placement of the transdermal patch that delivers the drug. We ...

Circuit board failures are often ignored because they could be impreceptible. This simulation examines how internal layers around a soldered pin via subject to temperature changes during the soldering process are affected, show the forces involved and determine breaking points. A 2D thermo-mechanical model of a soldered pin is achieved in two simulation steps. First, a connecting pin already ...

One of the methods to recover oil from medium and low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case the oxygen in the air burns the heavier components of the oil, generating a heat wave leading to vaporization of lighter components. The combustion mechanisms are different for light oils, where evaporation is dominant, whereas for medium non-volatile ...

A Dutch firm manufactures a mounting system to fasten roof workmen to the roof of a flat roof building to prevent them from falling down from the roof. The system is mounted to the flat roof afterwards, i.e. after the completion of the thermal insulated roof. Because of the mechanical strength and stiffness properties of the system, it is manufactured using (stainless) steel. The steel, ...

Wear is a complex phenomenon relevant to many problems involving frictional contact, such as mechanical brakes, seals, metal forming, and orthopedic implants. The rate of wear depends on the properties of the contacting materials and operating conditions. One widely used model of wear is Archard’s law, which relates the rate of material removal due to wear to the contact pressure, sliding ...
Phase-field Modeling of Widmanstätten Ferrite Formation During Austenite to Ferrite Transformation in Fe-C Alloy - new

The transformation of austenite (A) to ferrite (F) in steels, which is technologically important and of fundamental interest, still remains less well understood in some aspects. At intermediate undercooling F grows with a plate-like morphology (widmanstätten). Some calculations, which assume that the composition at A/F boundary is local-equilibrium or the morphology of F is rather simple, are ...
