The high flow rate within the HFIR cooling water flow channel causes the fuel plates to deflect which in turn, changes the coolant flow characteristics. This nonlinear feedback loop between the coolant and the fuel plate is the focus of the present simulation of the fluid-solid interaction between the coolant flow and the fuel plates to accurately predict the plate’s deflection using the Fluid ...

To maintain same droplet size across parallel devices, new break-up strategies based on geometry are been studied. In this work, we model a geometrically-set droplet generator, in which the droplet break-up occurs by a block and break mechanism. In other words when the disperse phase blocks the path of the continuous phase, droplet formation occurs. The devices showed consistent droplet ...

In previous works a dissipative hydrodynamic model was used to simulate the behavior of a dense granular solid flowing through silos with simple geometries or with internal devices, showing good agreement with experimental results. That model has been upgraded taking into account the interaction between the solid itself and a nonreactive gaseous stream flowing countercurrent through it. This ...

Enzyme reactions, blood flow and diffusion in human vasculature play interacting and fundamental roles in blood coagulation. In this complex mechanism, the balance between blood and clot is a delicate equilibrium, whose tight regulation is vital to avoid pathologies such as bleeding and thrombosis. The secondary hemostasis triggered by tissue factor in platelet poor plasma is studied up to ...
Investigating the Performance of Mechanically Ventilated Double-Skin Facades with Solar Control Devices in the Main Cavity - new

The use of ventilated facades may reduce the cooling and heating energy demands of the building. Double-skin facades (DSFs) belong to the wider group of ventilated facades and currently represent one of the most interesting and studied facade systems. The purpose of this study is to investigate the thermal behaviour and performance of a DSF being designed for a real project in the Middle East ...

Air permeability is one of the most important parameters in the study of thermo-physiological comfort of fabrics. The main goal of this work is to develop a virtual process that allows the prediction of air permeability of any fabric without realizing a sample. The Free and Porous Media Flow physics interface was used in COMSOL Multiphysics® software; this allows to use Navier-Stokes equation ...

Nanofluids is a new class of fluid consisting of particles in a liquid. Different base liquid has been proposed and the most common one is water. The concentration of these particles can range from 0.1% to 5% or greater. Different numerical models have been proposed to solve this interesting problem. Some scheme assumed the fluid as a single fluid and other assumed as a two phase system ...

Studies of the liquid metal movement (hydrodynamic) in a real object (tundish) are substantially precluded due to the objective difficulties (high temperature and the size of metallurgical equipment), compared to their execution by the use of physical and numerical modeling. In presented study, two test methods for analyzing the flow and mixing of the liquid steel in the tundish were used. The ...

Coal mines in many countries which rely heavily on fossil energy have huge CBM, coal bed methane, reserves. Meanwhile, methane extraction efficiency of low permeability coal seam is very low. It causes seriously waste of low-carbon energy source. For the sake of enhancing the efficiency of CBM extraction system and decreasing energy consumption of electrical equipment of CBM extraction system, a ...

Simple, accurate CFD simulations using COMSOL Multiphysics are used in a senior-level undergraduate course as a means to explore a number of fluid flows with the intent of developing a deep understanding of the underlying fluid mechanical mechanisms involved in the flows. Students also learn about the finite element method, how to properly pose the underlying mathematical model for the fluid ...
