Stockton University has one of the largest closed loop geothermal system in North America. It provides heating and cooling for the university academic facilities. The well field comprises of a grid of four hundred wells bored to a depth of 130m. The ground is composed of three aquifers of saturated sand sandwiched between confining beds and transition layers of sand and clay. The purpose of this ...

In the molding industry, high productivity rate, low energy consumption, large 3D parts, and homogeneous temperature distribution are the main targets. The 3iTech® inductive technology developed by RocTool ensures both good temperature homogeneity and short heating time. Conventionally, to guarantee efficient cooling, a turbulent water flow is directly integrated into the mold. Ideally, to cope ...

The study produced a simulated model of natural convection in an inclined rectangular channel open ended with different locations of radiant barrier (RB) along the channel thickness(S). The upper plate is heated by various uniform constant heat fluxes while the inner surface of the lower plate has a very thin layer with low emissive aluminum foil. This model was used to adjust the location of ...

The understanding of the tracer migration in two-phase porous media systems and its reaction over the fluid-fluid interfaces is a challenging task important for a number of engineering applications, e.g. oil recovery, carbon capture and storage in geological reservoirs, remediation groundwater contaminations, etc. The goal of this work is to implement in COMSOL Multiphysics® an immiscible two ...

One of the most critical aspects on water electrolysis is gas-liquid separation, especially in systems with forced convection. The main problem of this kind of circulation is that a gas fraction could return to the electrolysis circuit. A suitable design of separator devices could be a solution in order to avoid a gas return to the electrolysis circuit. In this sense, the use of deflectors might ...

The study of low Reynolds number flow around air vehicles of the order of centimeters. According to DARPA, a NAV is defined as a vehicle with 7.5 cm of length and weight of 20 grams. We calculated the flow around a small length scale 3D rigid body with complex geometry. Firstly we perform the numerical simulation of the two dimensional flow around a circular cylinder for 30< ReD

Liquid metals are foreseen as a multipurpose coolant in fusion blanket systems. However, the strongly magnetic environment of the fusion reactor hinders the regular flow of the liquid metal. It interacts with transverse magnetic field and produces a Lorentz force opposing the flow, modifying the regular flow profile in the circular pipe or rectangular ducts. Complex geometry and lack of ...

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 ...

Flexible and semi-rigid polyurethane foams are widely used as noise and vibration damping materials. Their porous random microstructure is composed of a visco-elastic frame structure with an interstitial fluid, normally air, filling the voids. The viscoelasticity of the foams is due to the polymer morphology in the foam skeleton structure, which can be adapted depending on application ...

Various types of equation system formulations for modeling two-phase flow in porous media using the finite element method have been investigated. These allow for equation manipulation such that the main differences between the formulations are the dependent variables that are solved for. Here we have tested five different formulations for 2D simulations and one for 1D; the Buckley-Leverett ...
