Students encounter cavity resonance and waveguide phenomena in acoustics courses and texts, where the study is usually limited to cases with simple geometries: parallelepipeds, cylinders, and spheres. At Kettering University, we are beginning to employ finite element modeling in our acoustics classes to help undergraduates better understand the acoustic modes of actual structures. This ...

We are testing the hypothesis that the simulation of laboratory equipment will solidify the link between experiment and theory and provide improved learning for senior chemical engineering undergraduates. We developed a simulation of an industrially important gas permeation experiment in which air is separated into an oxygen-rich stream and an oxygen-depleted stream using a hollow fiber ...
In this work, we present the principles of 3D scanning. 3D scanning is the process of taking an object in the real world and through finding the relative phase in camera coordinates and projector coordinates, produces a 3D model.

This paper reports a strategy to design a network of higher immunity and capacity of recovery to faults or other destructive events. The capacity of survivorship and recovery increases when the system possesses some redundancy, and this means sources and lines and switching capability that are able to take over areas that loose connectivity to their parent source. Therefore, a second network, ...

Tools are developed that mine the mesh and simulation data provided by the finite-element mesher and solver in COMSOL. The tools developed are used in two applications. In the first, a thermal system is decomposed and an equivalent circuit (EC) is developed for reduced order modeling. In the second application which arises in robotics, the COMSOL mesh is used to plan paths of the robot ...
Use of COMSOL Multiphysics for Efficient, Automatic Inverse Modeling of PDE-based Systems: Applications to Aquifer Characterization
M.A. Cardiff, and P.K. Kitanidis
Inverse Modeling refers to the practice of using measurements to estimate unknown parameters of a system, under conditions in which only a model for the forward problem is given. Here, we present a framework for the inverse modeling of PDE-based systems using COMSOL Multiphysics and MATLAB. Included in our framework is an automatic adjoint state formulation, allowing for more efficient ...

In the current paper, similar features for fast or turbulent, non-linear flows subjected to Forchheimer equations are analyzed. Under some hydrodynamic and thermodynamic constrains, it has been shown that there exists the so called pseudo-steady state regime for Forchheimer flows in reservoir media. This invariant is called diffusive capacitance, which is the mathematical model for the well ...

A membrane distillation process equipped with mesh-type material spacers has been modeled as a two-dimensional conjugate problem in which a simultaneous numerical solution of the momentum and energy of the feed and cold solutions have been carried out. The results shows that the center suspended spacer produces the highest average shear stress, and gives the highest spacer efficiency at all ...
